Partial Discharge Testing: Need, Testing Methodologies and Addressing Defects

Studies show that over 85% of disruptive failures in high voltage (HV) and medium voltage (MV) equipment are Partial Discharge related. Partial Discharge (PD) activity provides evidence  of deterioration in assets, which can propagate and increase, until the insulation is no longer able to withstand the electrical stress therefore leading to flash-over and finally equipment failure. Therefore, early detection …

9 Fundamental Tests For High Voltage Circuit Breakers

When it comes to the cohesive protection of man, machine and infrastructure from electrical mishaps, Circuit Breakers (CBs) play a linchpin role, especially in the high-voltage (HV) environment of Substations. With rapid advancements in technology, while the quality of HV CBs has definitely improved over the last few years leading to a significant drop in …
