Electrical insulation is the cornerstone of high voltage system reliability, serving to impede undesirable current flow and thereby prevent catastrophic failures. Integral to the performance of ...

For more than 50 years, companies have performed partial discharge (PD) testing on electrical assets as part of ongoing predictive maintenance programs. Data obtained through PD testing and monitoring ...

What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

The oscillating wave test system from HDW Electric can be used to identify, evaluate, and locate partial discharge (PD) faults in a cable insulation and in joints and terminations. The system can be ...

The measurement engineer can view the values from tan δ and partial-discharge testing directly in the cable test van. Clear representation helps to detect severe defects or locate partial discharges ...

As DC high-potential testing starts to show its age, test methods recommended by IEEE are ready to fill the void For many years, high-voltage DC testing has been the traditionally accepted method to ...
