Transformer Testing

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,...

ACCELERATING TOWARDS GREATER TESTING EFFICIENCY - A true transformer test van

Test lead management, including quality of connection and correct lead placement, is an important part of testing. Poor or incorrect connections can be the culprit for nonrepresentative results that ultimately lead to longer test times and, in some cases, wasteful investigations...

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 Role of Cable Rejuvenation in Addressing the Maintenance of Aging Underground Cables

Aging underground residential distribution (URD) cables is a growing problem in communities around the world, disrupting customers and causing business challenges for utility providers. But in most cases, the traditional remedy for URD cable failure—taking the impacted...

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 also last up to 10 times the expected lifetime than newer sulfur hexafluoride (SF-6) gas interrupters. Unfortunately, the downside to building a protective device with a long service life is that utility...
