“Practice Prevention to avoid Correction”
Partial discharge testing, also known as PD testing, is performed to assess electrical insulation health. PD is best described as a failure of part of an insulation system to withstand the electrical field applied to it. This can be a result of poor design, poor workmanship, defective materials, contamination, or aging. For decades it has been recognized that partial discharge testing is an excellent method for determining electrical asset health.
Online non-invasive and non-destructive techniques for monitoring and surveying have been proven to provide the necessary level of detail for condition assessment without impacting system operation. We'll discuss it further in this article.
Techniques exist now to test assets from 3KV to 700KV and beyond. Metal clad switchgear and buss work, GIS switchgear and busses, air insulated assets (insulators, arrestors, bushings, etc.), as well as paper insulated and extruded cables can all be tested online without an outage.
“Performance with quality is powerful combination. ”
Our engineers have extensive experience in the testing of Transformers, Generators, LV switchgear, and MV switchgear.

Our engineers have extensive experience in the testing of Transformers, Generators, LV switchgear, and MV switchgear.
We carry out cable fault location on either over ground or underground cables and provide an engineer to carry out safe electrical testing and identify the location of the fault.
