Commissioning
We have a dedicated team of skilled engineers to provide test and commissioning services for transformers, substation breakers, switches, instrument transformers and control and protection systems and switchgear.

Our commissioning engineers have many years of experience in the electrical power industry both in the United States and overseas.

For our commissioning efforts we have extensive training on the latest products from the main manufacturers of substation equipment, and we use the latest automatic computer programmable test equipment, such as: Megger, Hiptronics, Vanguard, Fluke, etc.

We can offer a full range of testing and commissioning services including the following:

  • Complete testing of power transformers including accessories and protective devices.
  • Secondary current injection for protective relays and systems.
  • CT testing including magnetization characteristics.
  • Testing of switchgear, cables and bus bars.
