Guest Article by Glen Bate (Panduit Account Manager)
When servicing LV MV HV electrical equipment, workers must comply with safety regulations that require a voltage verification test to validate the absence of voltage.
This process requires strict adherence to prevent accidents and bodily injury, but includes many stages that can be complex and time-consuming when using hand-held portable test instruments.
This paper examines the costs and limitations involved with using a manual absence of voltage tester. It also describes a new technology for the factory floor that automates the process, reducing time, complexity, and costs.
VeriSafeTM by Panduit is the first-of-its-kind voltage tester that determines the absence of voltage with just a push of a button. This revolutionary 2018 NFPA 70E compliant product automates the required six-step testing process in about ten seconds, enabling your plant to operate faster, safer, and more efficiently.
Simplify electrical safety with the superior technology of VeriSafe.
Historical Costs of Checking for Absence of Voltage
Numerous studies exist pertaining to injuries resulting from electric shock and arc flash events. These studies recognise that establishing the economic payoffs of prevention is a critical factor in promoting workplace safety. Besides personal injury, the costs of property and equipment damage need to be considered.
Although estimates vary, studies have shown that the average direct cost of an electrical injury ranges from about US $50,000 to US $80,000′, while the indirect cost can exceed the direct cost by a factor of nearly four2. Direct costs include lost wages or workers’ compensation payments, medical expenditures, and legal expenses.
Indirect costs include:
Electrical injuries have one of the highest average workers’ compensation costs, second only to motor vehicle accidents3.
Injuries from contact with exposed wiring, transformers, or other electrical components frequently occur in the workplace and involve construction, installation, maintenance, and repair workers. These injuries are often costly and serious, as demonstrated by the number of days away from work; 51% of workers missed over one week of work due to these injuries, with 40% missing two weeks or more4.5.
Limitations of Using a Handheld Voltage Tester
Verifying the absence of voltage is part of the process to establish an electrically safe work condition. Step 5 of NFPA 70E-2015 Article 120.56 describes this process:
Use an adequately rated test instrument to test each phase conductor or circuit part to verify it is de-energized. Test each phase conductor or circuit part both phase-to-phase and phase-to-ground. Before and after each test, determine that the test instrument is operating satisfactorily through verification on a known voltage source.
This process usually involves a portable, hand-held voltage test instrument. To be effective, it is critical to perform each step of the process in sequence, and it requires taking the necessary precautions, such as the proper use of personal protective equipment (PPE) (Figure 1).
Competent & Authorised Persons
Note Panduit recommend that VeriSafe should be used by competent and authorised people. As VeriSafe is a new and innovative solution to make the Absence of Voltage Testing, we recommend that the people who will use this device, have to be trained in order to understand how it works and how to use it properly.
Please be aware that with this product there is no risk of having hazardous voltage on the indicator module and on the door, as they are isolated from the main power by the isolation module which is located inside the panel. This means that there is less than 5 volts (just enough to power the LEDs on the indicator) present at the device located on the door and used to launch the test procedure.

Complexity
Adhering to this process prevents electrical injuries, but the process is complex and time consuming. Portable instruments are susceptible to mechanical and electrical failure and misuse by the person using the device. In addition, because the process of using a hand-held tester is dependent on human input, interaction, and interpretation, it is vulnerable to mistakes and errors.
Training Costs
Training on the selection, maintenance, and use of test instruments is crucial as are systems for inspecting and maintaining voltage test instruments. However, training and maintaining the test equipment incur the additional expenses of time and cost.
The Risks of Voltage Testing
Portable Handheld Voltage Detector in Action
Electrical Safety
Traditional Method – Determining absence of voltage with handhled testers presents a risk of exposure to electrical hazards
A disadvantage of implementing a voltage verification test with a hand-held tester is that the person performing it may be exposed to electrical hazards while verifying that the tester is working prior to and after the test, and during the test if the equipment was not de-energized.
With such a significant emphasis on performing work only on de-energized equipment, it is ironic that best practice relies on PPE and exposure to hazards before de-energized work begins. The need for PPE is a significant contributor to the overall time to carry out this process because the worker must first determine the required PPE, then obtain, inspect, dress, and properly store it after use. Additionally, PPE can be misused or not used at all, especially when there are time constraints.
When processes are overly complex or time-consuming, workers tend to become complacent and develop shortcuts as practices become routine. A normalization of deviance—small, gradual deviations from an established practice—may occur over time. With the lack of negative consequences, the lower standard eventually becomes the norm”.
Even when hazards are part of the everyday routine, deviations from a safety procedure can slowly become accepted practice. These deviations are particularly evident when there are time pressures, which is often the case when electrical maintenance causes unplanned or excessive downtime. If either training or enforcement of administrative procedures is lacking, the effectiveness of the procedures will diminish.
A More Efficient Way to Test for Voltage VeriSafeTM Absence of Voltage Tester (AVT)
VeriSafe AVT – Prevents direct exposure to electrical hazards and determines voltage status before equipment is accessed
The VeriSafeTM AVT automates the voltage verification process and is the first AVT tailored for electrical enclosures (Figure 2). By automating this process, the VeriSafeTM AVT features the following:
The VeriSafeTM AVT is applicable for several applications:
Figure 2 VeriSafe AVT
NFPA 70E
One of the major changes to the 2018 edition of NFPA 70E involves the new requirements that allow an installed AVT to be used instead of a hand-held voltage tester. When the VeriSafe– AVT is used in conjunction with a Lockout/Tagout Program, it meets the requirements for the process described in NFPA 70E-2018 Article 120.5:
Exception No. 1: An adequately rated permanently mounted test device shall be permitted to be used to verify the absence of voltage of the conductors or circuit parts at the work location, provided it meets the following requirements:
Figure 3 Comparison of the VeriSafe AVT and Portable Device Testing Methods
VeriSafe AVT – The Safe, Efficient, Accurate Way to Verify
Integrating the VeriSafe™ AVT is a vital improvement to absence of voltage testing. A solid testing method helps create a reliable, safe, cost-effective system that workers can use as needed. The VeriSafe™ AVT verifies the absence of voltage before equipment is accessed, making it easier for qualified electrical workers to determine an electrically safe environment in a fraction of the time required by hand-held portable test instruments.

The importance of distribution 11kV transformers as part of electrical infrastructure can not be overstated. As an asset that is always energised, regardless of whether they carry a load, transformers are critical assets and pivotal to ensuring that a safe level of voltage is supplied to businesses across the UK.
It is surprising then to consider that the performance and operation of them has been left offline and unknown apart from when subjected to annual manual inspections, particularly as Industry 4.0 gathers momentum and the UK continues to undergo digitalisation.
Fortunately, the advent of smart transformers has revolutionised this crucial asset and enables companies to access real-time insights into asset performance and operation through remote monitoring capabilities, ultimately enabling a holistic energy management system to be achieved.
The value of such characteristics is apparent in applications such as that of grid tied solar photovoltaic (PV) applications. In these applications, distribution transformers are utilised to directly connect generation from solar PV sources to the grid.
A benefit of grid tied solar (PV) applications is its ability to transform the DC power generated from solar modules into AC power that can be used on the network in a smooth transition without overvoltage.
This transition minimises wasted energy and therefore heightens energy efficiency, whilst the protection against overvoltage allows electrical equipment to continue operating at an optimal level and therefore minimise the risk of premature breakdown and the costs of early repair or replacement.
Additionally, the connection to the network allows those with grid tied solar to take part in the decentralisation of the energy network that forms a key part of the energy transition. This is because the grid connection through a transformer allows for the selling of excess generation to the grid and the asset owner to become what is known as a prosumer – an organisation that both consumes and produces energy.
When the site is utilising solar power, the energy has to be transmitted to the area of consumption, this is when the assets will transform the energy to ensure it is at the correct voltage either to export to the grid or to supply the site. Any interruption caused by a malfunction of a distribution transformer during this process can have significant consequences including wasted solar generation and loss of revenue if during a time of paid export to the grid.
Therefore, the ability to gain valuable insights relating to asset performance and operation can protect against such scenarios by allowing for preventative maintenance to be deployed when anomalous activity is detected, such as a rising temperature of the core.
The real-time responsiveness of the remote monitoring capabilities, such as those found within Powerstar SO-LO a super low loss amorphous core smart transformer with remote monitoring capabilities, enable detailed and easier management of all assets connected to the transformer and can highlight areas of further optimisation. These remote monitoring capabilities can deliver details, 24/7, on grid information, conditional performance data, energy efficiency reports and more from anywhere with a secure internet connection.
Super Low Loss Transformers Up To 11kV By Powerstar SO-LO
This takes on even greater importance in grid tied applications when considering the intensity of PV generators and the role they can play in the security of supply to a site and towards carbon neutrality goals.
Furthermore, smart transformers like Powerstar SO-LO provide greater efficiencies than traditional transformers due to the materials which they use. Instead of using cold rolled grain-oriented (CRGO) silicon steel like traditional distribution transformers, Powerstar SO-LO uses an amorphous alloy core. This is a more flexible material than CRGO and allows for easy magnetisation and demagnetisation to take place which leads to greater efficiencies, with up to 75% lower core losses achievable when using amorphous core compared to CRGO. This greater efficiency further enhances the benefits of grid tied PV.
It is clear that, as the energy transition progresses, the use of onsite generation such as solar PV is likely to become more widespread. However, to obtain the most benefit from onsite generation, particularly given the intermittent and often unreliable nature of renewable sources, it needs to be made as efficient as possible.
Grid tied PV through smart transformers represents a proven and reliable way of enhancing the efficiency of solar PV and maximising the benefits of onsite generation.
