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...

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...

Insulation Resistance Test

Insulation Resistance (IR) test, often called Megger test, is more than 100 years old and assumed to be a very straightforward test. During my inspection and testing work in the past 15 years in Canada, US, and internationally, I have seen different practices of performing and interpretation of IR...

Utility Proactively Tests Underground Cable

Distribution companies are continually looking for ways to improve system reliability, all while conserving capital investments and operational costs. With an aging infrastructure, one of the main issues that utilities face is a way to assess the actual condition of their capital assets. With...

Ground Tester Section Criteria

Ground Tester Section Criteria is important to decide. The electrical grounding component of an electrical facility can be easily overlooked. It doesn’t appear to have an active role. It isn’t moving, doesn’t emit light or sound, or provide data. It’s largely out of sight. But the electrical ground is in fact dynamic. It gets challenged and stressed like any other part of the electrical system. It can deteriorate and lose effectiveness. It should be checked,...
