HV & LV Installation


It is important when choosing an installation partner that you consider an engineering team with safety and experience at the heart of its business.

Our core team of engineers are all factory trained and many have spent time on the shop floor in assembly or inspection roles, all have many years’ experience working on site installing and subsequently maintaining industrial electrical equipment..

Our company has recently been awarded NERS (National Electrical Registration Scheme) approval, set up by Lloyd's Register, it operates on behalf of the UK Distribution Network Operators (DNOs), and is considered by many in the industry as the pinnacle of electrical safety.

  • 415V Low Voltage Switchgear
  • Package Substations
  • 11,000V Primary and Secondary Switchgear
  • Oil and Cast Resin Transformers
  • 33,000V Distribution switchgear
  • Busbar Trunking


After installation of the panels the following commissioning tests can be performed:

  • Complete functional check of internal panel wiring.
  • 5kV Insulation Resistance test on the panel busbar system
  • High Voltage AC pressure test on the busbar system of the panels (breakers and disconnectors open).
  • High Voltage AC pressure test on the busbar system of the panels (breakers and disconnectors closed).
  • Determination of the current transformers Magnetisation Curves.
  • Primary Injection of the current transformers (up to 600A).
  • Primary Injection of the voltage transformers.
  • Secondary Injection of the protection relays.

Our commissioning teams have recently completed 5 major installations for UKPN including the installation and commissioning of a 66 panel, 11kV, double busbar system.
