Screen & Semi-conductive Layer

On MV Medium Voltage Cables

Every wondered what the purpose of the screen and semi-conductive layer on MV cables was? Wonder no longer – Eccentricity’s Guest Blog covers it here.

In most modern medium voltage (MV) cables, especially underground, cables are shielded or screened with an earthing conductor. The screen consists of lapped copper tape or metallic foil usually less than 1mm in thickness, which is the interface between the conductor and the insulation (PVC, XLPE).

The main purpose of this conductive screen is to maintain a uniformly divergent electric field and contain the electric field within the cable core. The conductor screen is made from semi-conductive material, which is designed to hold back voltage.

This smooths out the surface irregularities of the conductor by making the voltage on the inside of the insulation the same. This semi-conductive screen material is based on carbon black, which is dispersed within a polymer matrix. The concentration of carbon black needs to be sufficient to ensure adequate and consistent conductivity.

It must also be optimized to provide a smooth interface between the conducting and insulating components of the cable, which is important as it decreases the occurrence of high stress regions on the cable.

The semi-conductive screen also reduces voltage stresses where the conductive components interface with the insulating components.

It accomplishes this when the expansion of the insulating layer is typically 10 times greater than that of the conductor, so that when the cable is at its maximum operating temperature of 90^oC a large enough gap is formed to allow electrical discharges to occur.

This then serves to even out the stresses associated with these discharges which would otherwise attack the insulation at specific points along the medium voltage cable.

The screen wires are connected at each extremity of the circuit in solidly grounded systems, dispersing the circulating currents of the MV cable.

When connecting the screen wires, it is important to note whether the installation is using current transformers (CT’s) for the circuit protection. Any currents on the screen wires will be phasor summed in the conductor by the CT. In the case of fault currents, this is often directly out of phase with the conductor current.

As the screen passes through the CT as part of the cable it is then necessary to bring the made-up screen wires back through the CT in the opposite direction prior to grounding. This ensures the screen current is effectively cancelled out to ensure the correct operation of circuit protection devices.

Interview with Paul Morrow from Klauke

ENERGYx2020

with Paul Finnegan & Louise Purcell (Energy Network Events)

Exhibiting at ENERGYx2020 in this informative interview Paul Morrow, UK & Ireland Manager for Klauke, part of the Emerson Group and world class manufacturers of cable cutting and crimping tools, discusses electrical safety and the recent launch of the KLAUKE Orange range of fully insulated tools that have set the standard within the global utility industry.

Health & Safety is a main pillar of Energy Network Events and the KLAUKE Orange range is a huge leap forward in the development of battery-powered cabling tools for the cutting and crimping of overhead lines and underground cables.

You can view the complete range of KLAUKE Orange tools here ➡ insulated cable crimping and cutting tools.

Energyxtra Interview

Paul Morrow describes how Klauke was started in 1879 by two brothers in Germany originally making high quality pliers for the watch-making industry employing only 5 people. In 1960 when electrification become more popular Klauke shifted to developing cable lugs.

In 2018 they were acquired by Emerson and along with Greenlee and Rigid, Klauke can now service all the mechanical, electrical and plumbing requirements in the market.

For even more safety, Klauke has now developed the world‘s first battery hydraulic crimping and cutting tools with Tri-Insulation Barrier.

Cable Cutting & Crimping

Insulated Tools & Total Safety

The world‘s first battery hydraulic crimping and
cutting tools with Tri-Insulation Barrier technology that provides users with 1.000V protection against
electrical shocks.

There have been several recent advances in cable cutting and crimping tool technology including data recording, bluetooth remote controls and pressure sensors.

All tools have become more compact making them more efficient for jointing and terminating cables in confined spaces as well as enhancing safety features.

Training, supervision, testing and PPE are all standards but what the KLAUKE Orange implements is another layer of electrical safety into the process.

You frequently work in close proximity of live lines and parts. You cannot take any chances.
You have ergonomic issues due to use of manual insulated tools. You want to work safe but with faster and more ergonomic tools.
Cables you perceive as not live, can turn out to be live. You want to be protected at all times.
Live line cutting is one of your safety critical tasks. You have to use safer tools for more protection.

Tri Insulated Barriers on Klauke Tools

During the interview, Paul stresses the importance of safe working practices including the physical aspect of the tool e.g. the body insulation of the cable crimping or cutting tool. The new Orange Line Tool uses a 3 level or tri-insulation system – the 3 level includes creepage distance, insulation material and oil within the system.

PRESS RELEASE: Solar Industry Relaxes Planning Laws For Large Scale Battery Storage

July 15th, 2020

Solar Trade Association

By Solar Trade Association

14th July 2020

The Government has announced it will relax planning legislation to make it easier to construct large batteries to store renewable energy, in a move which will see ministers introduce secondary legislation to remove electricity storage, except pumped hydro, from the Nationally Significant Infrastructure Projects (NSIP) regime in England and Wales. [1]

STA Chief Executive Chris Hewett said: “We welcome the decision to make it easier to deploy flexible large-scale energy storage technologies in the UK, which will help to further decarbonise and improve the resilience of our energy system.”

“The next steps in unlocking the potential of energy storage, and maximising the crucial role it can play in managing growing solar and wind output, are to provide greater access to flexibility markets, including the capacity market, and applying fairer network charging rules.”

“Our aim has to be to fully decarbonise these flexibility markets and minimise all use of fossil fuel generation.”

There is currently in excess of 13.5GW of battery storage projects in the pipeline, with 1.3GW ready to build, 5.7GW with planning permission and a further 6.5GW proposed. [2]

BundGuards | Substation & Transformer Oil Spills & Leaks Containment

July 3rd, 2020

BundGuards | Substation & Transformer Oil Spills & Leaks Containment

BundGuards

Substation & Transformer Oil Spills & Leaks Containment

The Andel BundGuard system was first conceived and developed in 1992 as a direct response to the needs of the UK electricity industry and the serious water-removal problems it faced at sub-station sites across the UK.

Since then many thousands of BundGuard units have been installed nationwide, protecting customer assets, site operators and the environment.

To be compliant with current regulations, all above-ground oil storage tanks that contain more than 200 litres of oil, must have secondary containment or a ‘bund’ to contain oil leaks and spills.

Most bunds are exposed to the elements and consequently are likely to collect and fill with rainwater. As a bund fills with water, the containment capacity is reduced and the risk of oil escaping by overtopping the bund wall in the event of tank failure is greatly increased.

It is therefore essential that robust measures are put in place to extract rainwater from exposed bunds.

Andel BundGuard is a cost-effective, self-contained and easy-to-fit automatic pump and alarm unit that is installed within a bund and works continuously and automatically 24 hours, 7 days a week, 365 days a year.

Using advanced circuitry and micro-controller technology, the BundGuard system discriminates between oil and water, keeping oil contained and expelling water from the containment area.

Andel

Large oil storage tanks and equipment such as electricity transformers may contain several thousand litres of oil and are also likely to be open to the elements. The bund will gradually collect rainwater and in time, the holding capacity of the bund can be significantly reduced.

As oil floats on water, once the capacity drops below 100% there is a risk of oil overflowing over the bund wall in the event of tank failure.

Thorne & Derrick can supply an extensive range of standard and customised Bundguards for the protection of medium/high voltage substations.

Bundguards

Andel’s BundGuard is a cost-effective, self-contained and easy to fit automatic pump and alarm unit which monitors and works around the clock.

The BundGuard system uses advanced circuitry and micro control technology to keep oil within the container and expel water from the containment area.

The BundGuard has a robust stainless steel pump and sensor unit located within the sump. The control unit activates the pump as required to remove only clean water safe to foul sewer or interceptor depending on the sites circumstances.

Andel’s BundGuard system has a number of failsafe systems in place and a range of visual and relay alarm outputs to ensure safety and allow for communication to remote monitoring systems.

The PPL BundGuard removes the need for regularly emptying the bund by waste contractors thereby reducing costs, the environmental impact and carbon footprint.
