Protective relay testing verifies that installed relays will trip correctly under real fault conditions, confirming settings, ...

May 20, 2009, UK -- Protective relay installations that are based on IEC 61850, the new international communication standard for electricity substations, can now be tested easily and conveniently with ...

The cost of component failures continues to increase as electronic products become more complex. Most component replacement costs are associated with marginal devices that become intermittent or fail ...

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 ...

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, ...

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 ...

Differential protection is best understood as a fault control philosophy rather than a component category. The relay itself is secondary to the scheme it enforces. Once a zone is defined, the system ...

Verification and diagnosis of complex switching operations in a test system has been made easier with the introduction of built-in self-testing capabilities to select models of Pickering Interfaces' ...
