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 ...

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

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 the integrity of insulation in motors, cables, transformers, and other ...

DALLAS--(BUSINESS WIRE)--Smaller, lighter and with a higher output power than any other comparable three-phase instrument, Megger’s new SMRT 36 smart protective relay test set is ideally suited not ...

Cooper Power Systems has designed its full-featured differential relay, the iXP-420, to provide comprehensive two-winding transformer protection, and monitoring and control. The iXP-420 incorporates ...

Schweitzer Engineering Laboratories, Inc. has announced three new additions to the popular SEL-787 family of differential protection relays, providing low-cost, versatile transformer differential ...

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 ...

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 ...
