Cable Testing Comes of Age - One Cycle at a Time

Field Testing of MV and HV cables has come a long way in recent decades. Gone are the days of old, when the traditional DC (Direct Voltage/Current) hipot was the recommended method for testing these modern cables that form the critical backbone of the distribution electrical power network....

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...

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...

The End of the Road for Transmission Incentives

In a significant shift, the Federal Energy Regulatory Commission (FERC) has decided to abandon its transmission incentives policy, particularly the construction work in progress (CWIP) incentives. This decision marks a pivotal change in how transmission projects are financed and regulated,...

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...

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...

Detect Electrical Discharge Defects with Ultrasound

Electrical discharge is more common than we’d like to believe; even in new installations. Detecting these defects poses a serious challenge, particularly at an early stage when there is still time to initiate corrective actions. Vigilant technologies help reduce the risk of arc flash explosion while enhancing the overall reliability of electrical assets.
While there is no one perfect inspection technique or technology which can, on its own, detect and localize every defect, ultrasound performs...
