Wiring method for relay protection cabinet
This handbook covers the code of practice in protection circuitry including standard lead and device numbers, mode of connections at terminal strips, colour codes in multicore cables, dos and donts in execution. Also principles of various protective relays and schemes including special protection. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. The selection and applications of. At its core, wiring a relay is about using a small, gentle electrical signal to boss around a much bigger, more powerful one. You'll connect a low-power control circuit to the relay's coil (terminals 85 and 86), which then flips a switch for a separate, high-power circuit running through the.
