FERC Complaint Targets Duke, PJM Transmission Planning

A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...

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...

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...

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....

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...

Transformer Diagnostic Testing

Transformer diagnostic testing: standards to diagnose equipment with Sweep Frequency Response analysis BY VOLNEY NARANJO, Megger Sweep Frequency Response Analysis (SFRA) has become a powerful tool in advanced power transformer assessments and probably one of the main and first tools used to...

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...
