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 ...

Testing relays is both an art and a science. As relay technicians inevitably learn in the field, pure theory-based understanding of protective relays is not nearly enough for the real-world situations ...

Proper selection and effective testing can increase contact reliability in the end product while reducing the overall cost of using relays. Who said relays are pass�? While electromechanical relays ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...

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, ...
