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 ...

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 ...

A new series of relays, called Interfacers by developer, Releco, a unit of Turck Inc., are more flexible and have features designed to minimize downtime. Interface relays connect computers and PLC ...

The 78 series 10-A relays are available with a variety of options, including a push-to-test button and a green LED status lamp. The ice-cube-style industrial relays use quick-connect, plug-in/solder ...

(MENAFN- GetNews) A relay module is a small electronic device that allows low-power signals to control high-power equipment. It works as a bridge between a control system-such as a PLC, Arduino, or ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...
