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 ...

IEC 61850 is the new international communication standard for substations. The main goal of 61850 is to obtain interoperability between different protective devices from different vendors. IEC 61850 ...

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 ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...

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 ...

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, ...
