Solving Underground Cable Problems with Partial Discharge Testing

How to prevent failure with partial discharge testing BY HENNING OETJEN, Megger Partial discharge (PD) measurements are increasingly used as a reliable and non-destructive diagnostic method to detect weak spots in the insulation of underground cables. Routinely, partial discharge measurements are...

Breaker Testing

Dynamic Resistance Measurement

Condition testing of circuit breaker’s arcing contacts BY BUDO MILOVIC, DV-Power The preventive maintenance on a high-voltage (HV) breaker consists of several routine tests. The timing and motion tests are methods used to assess the breaker’s mechanical condition. When the timing and motion...

Vacuum Interrupter Testing for Circuit Breakers

How to predict field life using vacuum interrupters BY FINLEY LEDBETTER, Group CBS Utilities have widely replaced older air-magnetic and oil interrupters for circuit breakers rated at one kilovolt (kV) or higher with vacuum interrupters (VI) due to higher interrupt capability. Vacuum interrupters...

Line Leakage Testing: Is It Right For Your Application

The Line Leakage test (LLT for short) is most often specified to be performed as a type test in a design or engineering laboratory or as a routine production line test on medical devices right before they ship. Not as commonly performed as a Dielectric Withstand or Ground Bond test in a production environment, LLT can cause some confusion for engineers and technicians alike.

However, technological advancements have begun to lessen the outward complexity of...
