Typical values of relay protection branch coefficient
Typically, 5A secondary although 1A secondary is available. Can be single or multi ratio (MR). Rule of thumb, select a ratio slightly larger than the rating of the circuit to be protected. The faster the protection operates, the smaller the resulting ha-zards, damage and the thermal stress will be. Also principles of various protective relays and schemes including special protection. Abstract: Information on the concepts of protection of ac transmission lines is presented in this guide. Many important issues, such as coordination of settings, operating times, characteristics of. The booklet gives a basic introduction to application of protection relays and the intent is not to fully cover all aspects. The intention. Typically added to a breaker close circuit to prevent accidental reclosure after a trip. This signal level is typically 5A nominal.
