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 ...

With its ease of configuration and its comprehensive range of facilities, including a variable-frequency voltage source with a continuous phase-shift function, Megger’s new self-contained SVERKER 780 ...

ISA has announced the new DRTS 66, a powerful and accurate test set for protective relays, energy meters (class 0.1) transducers and power quality meters. ISA has announced the new DRTS 66, a powerful ...

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 ...

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 ...

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 ...

Complying with reliability standards requires considerable resource planning. The tools and suggestions provided here may help engineers conform to new generator relay loadability requirements. But ...
