Overall, certification bodies for relay protection play a significant role in ensuring the quality and reliability of protective devices used in electrical power networks. Their evaluation processes help maintain the integrity of power systems, promoting safe and reliable. CE Marking CE marking is a mandatory conformity mark for products sold in the European Economic Area (EEA). Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. 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.
