High Voltage Testing and Commissioning

Our Engineers and Technicians are experts in all aspects of high voltage testing and commissioning, including plant, protection and control systems, testing and commissioning of new systems, as well as maintenance of existing systems.

Our involvement in many highly complex projects, over a wide range of sites and electrical systems, has seen us working simultaneously across installation and commissioning of complex protection and control schemes for high voltage electrical generation, transmission and distribution installations, investigative works for fault identification, and maintenance of existing installations to ensure compliance with relevant standards and codes.

Our services include:

  • High voltage protection schemes
  • SCADA system commissioning
  • High voltage transformers up to 500MVA
  • Circuit breakers (LV and HV)
  • Current transformers
  • Voltage transformers
  • High voltage switchboards
  • High voltage ring main units
  • High voltage earthing systems
  • HV cables
  • DC insulation resistance and polarization index
  • Transformer ratio tests
  • Winding resistance tests
  • High voltage substation testing
  • Dielectric loss angle tests (DLA)
  • Partial discharge tests (PD)
  • Ring flux tests
  • Recurrent surge oscillograph (RSO) tests
  • Thermography (thermal imaging)
  • Current transformer (CT) testing
  • Oil quality analysis
  • Protection relay & scheme testing and upgrades
