The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

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 ...

Relay testing is one of those challenging areas where there never seems to be a shortage of questions. The technology adopted in both the relays themselves and in the equipment used to test them is ...

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, ...

Distributed generation, also known as embedded generation, is a hot topic at the moment. With more and more generation being connected to the network, those concerned with its stability have to deal ...

Explore why relay protection testing is becoming more complex with IEC 61850 systems, and discover practical steps to streamline your protection workflows. If you’ve been in protection testing for a ...
