CEO / High Voltage Specialist at HV Training and Consulting Pty Ltd "Every worker can go home at night after a day at work"
Thorne & Derrick International would like to thank Pat Mynett for allowing us to publish his article Overcoming Arc Flash Hazards.
Pat is CEO at HV Training and Consulting Pty Ltd and is a High Voltage Specialist.
In 2014, Pat Mynett decided there was room in the market for another RTO to provide quality electrical training. Especially from a person with recent industry experience, whose main interest was in the electrical safety of workers and the welfare of the plant. Arc flash safety training was a glaring omission in the industry so he developed, wrote and registered a nationally accredited arc flash course for those who work in an arc flash hazard zone.
This is Part 3 in a series of articles about the dangers of arc flash – over the course of these articles we have discussed the definitions, dangers, statistics, causes, prevention and protection against arc flash.

- Overcoming Arc Flash Hazards
Arc Flash
An arc flash can cause minor injuries, third degree burns and potential death as well as other injuries including blindness, hearing loss, nerve damage and cardiac arrest. Fatal burns can occur when the victim is several feet from the arc. Serious burns are common at a distance of 10 feet – arc flash can generate heat 4 times greater than the surface of the sun.
The Energy In An Uncontrolled Arc Flash
Arc Flash is the result of a breakdown in insulation which in turn causes an excessive flow of current between phase and earth, phase to neural or phase to phase. This current flow may be thousands of amps, that is why arc flash fault current is measured in kilo Amperes (kA).
The energy released from an arc flash is governed by the systems voltage, the generation capacity available, the impedance to the source and the time the fault is on the system.
Arc flash is made up of molten metal, plasma, intense heat, intense light, gas, intense sound, and pressure waves, all released in milliseconds.
Arc Flash Energy In Perspective
To get some idea of the energy that can be released: a 415 volts system with 5000 amps/ 5kA of fault current flowing for 500 milliseconds or 2500 amps/2.5kA flowing for 1 second, it would have a similar energy release as one stick of explosive.
A 200kVA transformer’s fault current at the 415-volt terminals can be up to 6170 amps.
A 100kVA transformer’s fault current at the 415-volt terminals can be up to 3085 amps.
Both having the capacity to produce the energy shown in the paragraph above.
How Is The Energy From An Arc Flash Measured?
Firstly, the energy at the arc flash source, is different from the energy received from an arc flash. It all depends on where you stand. So, the energy received depends on the distance to the arc flash source.
The energy received from the arc flash is called Incident Energy.
It is measured in calories per centimetre squared, (cal/cm2).
Incident Energy is: The amount of energy impressed on a surface, a certain distance from the source, generated during an electrical arc event.
So What Actions Can Initiate An Arc Flash
You will notice that all of the below, are actions that happen very frequently but only a very few ever initiate an arc flash. They are not normally the cause, there is usually other contributing factors,
1: Opening or closing a circuit breaker
2: Racking a circuit breaker in or out (see picture below)
3: Working live
4: Opening or closing a switch
5: Opening or closing an isolator
6: Dropping tools
7: Testing
8: Replacing parts
What Initiates & What Causes An Arc Flash
Are Different In Many Cases
Because the initiating actions, are actions that are all part of normal operations carried out frequently by many electrical workers, very little thought is given to the action itself.
Just as an example: A circuit has been modified. (AS/NZS 3000 specifies the circuit must be tested before re-energisation) yet many ignore this testing. The circuit breaker is closed without thought and there is a fault with the modification. The closing of the circuit breaker initiates an arc flash at the modification. If the circuit breaker has not been maintained, it may not clear the fault as per the trip settings time, it may not clear the fault at all, or another arc flash may occur at the circuit breaker.
Initiation Causes
1: Closing a circuit breaker – Closing onto a short circuit, the circuit breaker is under rated
2: Racking a circuit breaker in – Racking in a closed-circuit breaker onto a load
3: Closing a switch – Closing onto a short circuit and the upstream protection is incorrect
4: Opening an isolator – Opening an isolator with load on the circuit
5: Dropping tools – Working in a live switchboard with uninsulated tools
6: Testing using a non-rated multimeter with the settings on the wrong function
7: Replacing parts – Long tails make contact with live parts
8: Working live ignoring legislation, such as peer pressure not to turn the supply off

Causes Can Often Be Traced To Human Performance
Let’s look at some human performance issues.
Not concentrating, “I’ve always done it this way,” rushing to finish the job, taking short cuts, ignoring standard procedures, lack of knowledge etc.
One of the biggest issues with arc flash, is the lack of knowledge. Most electrical workers have heard of arc flash and have some idea of the results but have little understanding of arc flash hazards and mitigation of the hazards.
A few years ago, it was taken as an occupational hazard that electrical workers would occasionally get injured or die from exposure to an arc flash. This should not be the case today as arc flash is now a recognised foreseeable occupational hazard.
Where Do We Stand Under Law?
Australian Health and Safety law is quite specific about occupational hazards.
Australian Model Work Health and Safety Regulations: Chapter 3 General Risk and Workplace Management
34 Duty to identify hazards
A duty holder, in managing risks to health and safety, must identify reasonably foreseeable hazards that could give rise to risks to health and safety.
35 Managing risks to health and safety
A duty holder, in managing risks to health and safety, must:
(a) eliminate risks to health and safety so far as is reasonably practicable; and
(b) if it is not reasonably practicable to eliminate risks to health and safety—minimise those risks so far as is reasonably practicable.
As arc flash is now a foreseeable occupational hazard, so there is a duty to manage these hazards. Yet many companies choose to either ignore or play lip service to arc flash hazards.
Understanding Arc Flash Comes From Quality Training
Training workers is one area where little is happening.
Some large companies consider a familiarisation session of one hour as adequate training.
To cover training adequately takes 5 to 7 hours to cover what is required. Training should include; what arc flash is, Legislation & Standards, definitions, incident energy, causes of arc flash, PPE selection and requirements, arc flash risk management.
Protect Yourself Against Arc Flash
Arc flash protection is provided by specialist clothing and garments for “head-to-toe” protection.
Enhanced and effective arc flash protection is safely achieved by wearing layers of protective clothing and garments manufactured from inherent fibres and which feature specific Arc Flash resilient components. Without the correct high-quality garments arc protection levels will be compromised.

MV Terminations | Incompetency & Substandard Jointing Plumbs Another New Depth
July 11th, 2019
Contributed By: Watkins and Jacomb Construction Power & Consultancy
Uploaded By: Chris Dodds – Thorne & Derrick: Distributors of LV, MV & HV Cable Jointing, Cable Terminations, Substation & Electrical Eqpt
WJCPC are specialist LV HV Cable Termination & Jointing contractors with over 20 years experience in the High Voltage Electrical Industry covering the utilities, renewable energy, rail, data centre and general industry sectors – UKPN competent for LV & HV Termination and Jointing Of Cables, Confined Spaces, Substation Entry and Cable Fault Finding.
In the following post Ben Jacomb, Director of WJCPC, highlights several shortcomings and the dangerous consequences of clients failing to carefully vet and selectively employ Competent Cable Jointers.
WJCPC were asked to attend site to remove a total of 16 incorrectly specified and installed cable glands and install correct type brass glands. Due to the cable termination being a larger diameter to permit the existing and replacement cable glands to be changed WJCPC had to carefully remove the anti-track heat shrink (red insulation) from the heat shrink terminations.
After first inspection WJCPC were unsatisfied with the cable jointing technique undertaken to remove the semi conductive layer from the MV cable: this was done by using a semi-con stripping tool, the semi conductive layer is semi bonded so the stripping of the layer should be stripped by using a depth knife and the ringing of the stress control point by a soft file.
Any marks left in the XLPE insulation by the Jointer will influence the magnetic fields inside the MV cable and should be removed by emery cloth to leave a smooth finish eliminating any voids. If the heat shrink tube is shrunk on top of a void there will be moisture and where there is moisture there will be arcing, burning and then failure.
If the semi conductive layer is not removed correctly at the crucial point discharges occur and can damage the medium voltage cable and safe operation of the power network.
Below are WJCPC’s site observations.
Incorrect cable gland installed
The cable installed is a 11kV single core power cable with XLPE insulation and 120sqmm stranded copper conductors (16sqmm earth wires) – the original cable glands installed were 50mm plastic glands which are over-sized and incorrect for the cable diameter consequently failing to provide adequate mechanical retention.
Also, due to the cable being a backup supply from generators the vibrations will evidently loosen the cable gland until it is effectively and dangerously removed from the gland plate of the cable box which will then allow the cable to move around within the termination box – this could potentially loosen the cable termination connection.
This could do serious damage within the generator.
New 40mm brass cable glands were installed to the correct specification and that corrective action by WJCPC now has eliminated any vibration and loosening of the connection issues.
Observations
Ensure that when ordering jointing materials that manufacturers recommendations and specifications are met to eliminate incorrect installations.
Incorrect Cable Gland Installed
Over-Crimped Cable Lugs
All 16 of the site 11kV cable terminations had been over compressed or “crimped” due to the Jointer using an incorrect crimping die set.
Over compression of the cable lugs caused a distinct gap between the cable lugs and the cable insulation.
| Incorrect Cable Lug Compression | Correct Cable Lug Compression |
 |
 |
- Choose a manufacturer providing crimp tooling die set and lugs matched to work together to give assured crimping performance.
- Each lug should be clearly marked with a reference on the barrel or palm which enables the user to verify that the lug selected is the correct size and type for the conductor. The manufacturer’s name or logo also allows the correct die set and crimp tool to be selected from their recommended list.
- Prepare the conductor by stripping the insulation back so that, when assembled, it cannot be trapped in the barrel of the lug. The strip length should be equal to that of the barrel. Take care to avoid damage to the conductor strands during the stripping operation. Exposed conductor strands should be cleaned to remove any particles of insulation.
- Fully insert the conductor into the barrel. If an inspection hole is provided, check the conductor is fully inserted.
- Crimp the lug in accordance with the manufacturer’s instructions. Pay careful attention to the positioning of the die on the barrel and, if multiple compressions are required, the sequence in which they are made.
- For further information visit Cembre | Cable Lugs & Crimping Tools.
Examine The Completed Cable Crimp Lug To Check
- Marking on cable lug shows it is correct for the conductor type and size.
- The marking on the cable lugs show the correct die set was used.
- No insulation is trapped in the cable lug barrel.
- Excess grease is removed from insulation and lug.
- If an inspection hole is provided, the conductor has been fully inserted
- It is NOT to be over-compressed causing excessive flash or burrs, which are detrimental to the performance of the joint.
It is NOT under-compressed, as this is detrimental to the performance of the joint.
If any doubt exists, samples should be produced for test purposes.
Poor Cable stripping
of semi conductive layer
The semi conductive layer of the MV cable has been stripped by a stripping tool and on one occasion the stripping tool has impeded past the manufacturer’s requirements for their insulation diameter which will cause a void within the cable termination – the void could cause a hotspot and potential flash over which will render the connection irreparable.
The semi conductive layer is semi bonded (easy peel) so the semi conductive layer should be removed using a specialist Jointers tool or depth knife – here the semi con layer has been removed from the cable using a bonded semi-con layer stripping tool and it has left a poor finish to the XLPE insulation.
Even if the semi con layer is bonded type then the cable jointer should use 3 stage emery cloth ( 80, 120, 240 grit) to sand out any ridges and voids and then clean down the cable with a non- conductive cleaning cable wipe.
Poor Stripping By The Jointer Of The Semicon Layer Of The MV Cables
The XLPE insulation finish on easy peel type cables should be a nice smooth finish without ridges, undulations or jagged surfaces.
The semi con round off point should be a perfect finish as this is the most crucial point of the cable termination – if this is not perfectly smooth and the void filler mastic is not installed properly this can affect the stress relief from electrical fields.
It is essential this is undertaken by the Jointer with due care and attention.
Below is a photo of potential damaged caused by above non-conformances.
Missing earth strands from cable
On 50% of the cables WJCPC found missing earth strands. This will degrade the earthing protection for that cable.
Missing Earth Strands From Cable
Poor outer sheath strip
The outer sheath on occasions was poorly removed and not stripped according to the manufacturers jointing instruction – this may affect the damp seal which is installed on the outer sheath and the cable terminations measurements may come out of sync and affect the electrical connections durability.
Poor outer sheath strip
Conclusion
After full inspection WJCPC found that poor Jointing and sub-standard workmanship without quality control had introduced serious and potentially catastrophic operational issues into the medium voltage cable and power system network.
WJCPC recommend that a survey onsite is conducted to check more cable terminations as they suspect this will be a continuous issue onsite – using a thermal camera and partial discharge tester can help determine any cable terminations that need to be looked at and maybe pick some at random to strip down and visually inspect.
Due widespread concerns about industry workmanship, lack of Jointer training and declining standards, WJCPC can provide an audit service to visually audit jointers and ensure they are completing their termination to the manufacturers jointing instruction – this may not eradicate Jointer incompetency but it will contribute to a reduction in the volume of poorly installed cable joints.
There is also another process you can introduce and this is a step-by-step photo sequence of the termination installation at its crucial stages – this does not take long and captures the poorly installed cable joints or terminations before they are energised.
➡ Please Note: The cable glands WJCPC have changed and the re-termination of the cables will not be guaranteed by WJCPC due to the terminations not being installed to the manufacturers instructions. WJCPC have terminated them to their best ability but only as a temporary measure to allow the generators to be commissioned.
WJCPC strongly advise these cables are removed and new cable and new terminations installed immediately.

IEEE 1584 Arc Flash Standard | An Interview with Jim Phillips P.E., MIET
June 25th, 2019
IEEE 1584
Arc Flash Standard
Special thanks to Rebecca Frain CMgr FCMI Tech IOSH (Managing Director – Electrical Safety UK Ltd) for allowing Thorne & Derrick to publish her interview with Jim Phillips regarding the new IEEE 1584 2018 Edition.
What Is IEEE 1584?
IEEE 1584, published by the IEEE Standards Association, is A Guide for Performing Arc-Flash Hazard Calculations.
This guide provides mathematical models for designers and facility operators to apply in determining the arc-flash hazard distance and the incident energy to which workers could be exposed during their work on or near electrical equipment.
By Rebecca Frain
This week I had the opportunity to interview Jim Phillips regarding the new IEEE 1584-2018 Standard and what to expect with some of the new changes. In addition to being Associate Director for Electrical Safety UK and founder of Brainfiler.com, Jim is also Vice-Chair of IEEE 1584 and International Chair of IEC TC 78 – Live Working.
IEEE 1584 – IEEE Guide for Performing Arc Flash Hazard Calculations was first published in 2002 and is the standard that defines the equations and methods used in many of the arc flash software packages used for arc flash risk assessments. The second edition was published towards the end of 2018 and is a real game changer.
RF: A question many of us have is why did it take 16 years to publish the second edition of this standard?
JP: It has been a long journey. The timeline had many phases during this epic project. The first couple of years were spent developing a test plan and raising money from contributors for this enormous (and expensive) project. This was followed by preliminary tests that we call “Scouting Tests” These were used to help define the direction of the entire testing program.
After the preliminary tests, it took several more years for the project team to complete the main arc flash tests and develop the new model. That phase of testing was completed in 2012 and included over 1800 new arc flash tests. Quite an accomplishment. The 2002 edition of the standard was based on around 300 tests.
After the testing and model development phase, the IEEE 1584 working group created a model review task group to review and validate the new model. This took several more years of effort. During that time there was lots of fine tuning to further improve the accuracy. We completed it all in 2016 when it was now time for the formal balloting process. An interesting side note, the new standard passed on the very first ballot – we were all amazed. However, there were also over 1000 comments from the balloters that we had to address. Needless to say, this took some time to resolve. The second edition of this landmark standard was finally published on November 30, 2019
RF: What has changed with the 2018 edition?
JP: (laughs). It’s actually easier to answer the question “What did not change?” The standard still has the same title. With only a few exceptions, just about everything else is very different. This means what you previously knew about the IEEE 1584 standard can be tossed out.
RF: What is the single biggest change?
JP: That one is easy. The introduction of electrode configurations. The 2002 Edition had only two configurations: 1) An arc flash in an enclosure and 2) An arc flash in open air. Both were based on the test electrodes in a vertical configuration.
There are now five different electrode configurations: Vertical electrodes in an enclosure (VCB) and in air (VOA) which are the same as the 2002 standard but we also have horizontal electrodes in an enclosure (HCB) and in air (HOA) and vertical electrodes in an enclosure terminating in an insulating barrier (VCBB). The idea is the new configurations provide greater flexibility for modeling actual equipment.
RF: How does that affect the risk assessment?
JP: Depending on where the arc flash occurs and the type of equipment, the orientation of the electrodes, can affect the trajectory of the plasma and incident energy that reaches the worker. There is some guidance provided in the 2018 Edition of the standard.
RF: I assume there are other big changes?
JP: Yes. There are adjustments for different enclosure sizes. The enclosure size can have quite an effect on the incident energy. If an arc flash occurs in a smaller enclosure, the arc energy is more focused resulting in greater incident energy reaching the worker. If the enclosure is larger, the energy is not as focused and less energy reaches the worker. As a result, the tests included new enclosure sizes and the development of an enclosure size correction factor for the calculations.
RF: Anything else?
JP: The standard now uses interpolation and extrapolation to fine tune the results and provide better accuracy. There is also a new more detailed calculation for determining the minimum arcing current during an arc flash. The past standard simply used a fixed 85 percent value to determine the minimum.
The new equations are much more complex including a thirteenth-degree polynomial with thirteen coefficients that are selected based on the voltage and electrode configuration. (I hope I didn’t scare anyone away with that comment) The good news is the software takes care of the difficult math for us. The list of changes goes on.
RF: How does this all affect the results from previous studies?
JP: I have a series of worksheets that I developed and use to illustrate the calculations and compare with the 2002 edition. Some calculation results are similar to 2002. However, some can be quite different. It has quite a bit to do with the electrode configuration and other factors such as enclosure size.
RF: Does this change way arc rated clothing and PPE is selected?
JP: The overall risk assessment process is the same as before. i.e. Arc rated clothing and PPE are selected with an arc rating sufficient for the calculated incident energy. However, the difference is with the incident energy calculations using IEEE 1584. The calculations and modeling have changed dramatically.
Arc rated protective clothing is based on the standards: IEC 61482-1-1 and IEC 61482-2. There are a few other IEC standards for arc flash protection as well. These standards are from the IEC TC 78 Committee that has a group of highly knowledgeable and talented experts from around the globe all working towards developing and maintaining product standards for greater worker safety.
RF: We are looking forward to hearing more about the 2018 Edition of IEEE 1584 on September 24 at the upcoming International Arc Flash Conference in Manchester.
JP: Thank You Becky! I am looking forward to it. See you soon!
