Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

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.

Even the best relays can fail at some point, but what causes them to fail? Conventional wisdom lays the blame on worn-out contacts. And there is some truth to that view. Every electromechanical relay ...
