How well do you know the basics of how protective relays are configured, how they operate, and how to test them? Take this quiz and check your knowledge. Our thanks to AVO Training Institute for ...

Hands‐on testing and commissioning of substations in the real world can be daunting and dangerous without the proper training. So, TRC’s Testing and Commissioning group is building a training lab in ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...
