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 ...

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

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 ...

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 ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...
