Relaytestingprocedure Pdf Pdf Relay Switch The relay testing handbook is a practical resource written by a relay tester for relay testers; it is a comprehensive series of practical instructional manuals that provides the knowledge necessary to test most modern protective relays. Before testing the relay, you should have a clear idea about the terminals of the relay. the first step is identifying the primary side or the coil terminals. for an automotive relay, the coil terminals are 85 and 86. the next step is identifying the terminals of the secondary side: no, nc, and com terminal.
Function Test Relay Pdf Relay Transformer Do a basic visual inspection of the relay. many relays have a clear plastic shell containing the coil and contacts. visible damage (melting, blackening, etc) will help narrow down the issue. most modern relays have an led to tell you if they are in the active state (on). Using a step by step process. each detailed test plan must also provide an explanation as to why the test is useful to perform such as preventing a common type of mis operation from re occurring; for example, transformer differential protection tripping during energ. The procedure allows you to verify that the operation and settings of the relays are in good condition and to check the actuation time of each function. this document establishes the procedure for performing electrical tests on protection relays. A relay may only need to operate for 0.15 seconds in its 30 year life. but failure to operate as intended can result in extensive damage, extended power outages, and loss of life. neta (international electrical testing association) reports show 12% failure rates on protective relays tested. a comprehensive testing program should.
