Traditional testing methods can still be used to test 61850 devices with the MPRT IEC 61850 is the new international communication standard for substations. The main goal of 61850 is to obtain ...

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 ...

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 ...

Anyone who assumes that passive or electromechanical components are simple is either naive or inexperienced. Even a basic, functionally simple component such as a high-power, milliohm current-sense ...
