A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...
Smaller, lighter and with a higher output power than any other comparable single-phase protective relay test instrument, Megger’s new SMRT1 smart protective relay test set is suited not only for ...
Testing relays is both an art and a science. As relay technicians inevitably learn in the field, pure theory-based understanding of protective relays is not nearly enough for the real-world situations ...
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 ...
An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...
Aimed at panel builders, system integrators and process control applications, the HF115FP is available in single and double pole versions, rated at 16A and 8A consecutively. Showing versatility, the ...
