Heavy Electrical Equipment Testing

Together with our partners we have the capacity to carry out aLL types of Electrical tests and inspection work on all major equipment from Low to medium voltage switchgear to HV testing of Generators, Transformers, Switchyards, Power cabLes, Isolated Phase Bus Ducts, Gas InsuLated Switchgears etc. We have extensive experience in the Installation, testing and commissioning of such equipment, Here is a List of some of the testing for which we have the capability to carry out,
