A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

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 ...

AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...

Mitsubishi Electric recently visited EnergyVille, a collaboration between the Flemish research partners KU Leuven, VITO, imec and UHasselt, to install a prototype of its HVDC line protection relay ...
