Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

The PGT-0400 is a ground-fault-relay test unit designed to test current pickup level, time-delay and coordination of ground-fault protection. The tester injects current through the window of installed ...

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 ...

The Barrington Model Circuit Breaker Simulator was designed to be a convenient, lightweight alternative to operating high-voltage circuit breakers while testing the operation of substation protection ...

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 ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

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 ...

In-circuit test (ICT) has been instrumental in identifying manufacturing process defects and component defects on countless varieties of populated printed circuit board (PCB) assemblies for more than ...

Panasonic Industry has announced the launch of its latest relay, the HE-R, which has undergone enhanced short circuit testing to deliver a reliable and safe solution for customers in the EV charging ...
