Tests of distance relay teleprotection schemes should check both relays simultaneously, including their communication link. This video shows a real test of a 110 kV overhead line. The protection was ...

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 ...

Testing verifies that protection schemes meet their intended purpose, ensuring safety and system integrity. Function testing involves manual or electrical manipulation of components to confirm signal ...

Megger’s new SMRT 36 smart protective relay test set is suited not only for testing today’s installations and legacy plant, but also for meeting the future challenges associated with testing the smart ...

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 ...

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 ...

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 ...
