Protection coordination
Based on all these aspects, the opti-mum protection scheme is devised, which provides the customer the tech-nically and economically best solution. Selective protection coordination and relay
Line relay protection coordination
Relay coordination refers to setting protective devices so that the relay closest to the fault operates first, while upstream relays act as backups. Selective short-circuit protection can be achieved in different ways, such as: Time-graded protection Time- and current-graded protection A straightforward way of obtaining selective protection is to use time grading. The principle is to grade the operating times of the relays in such a way that. The scope of study involves calculating the settings for protective relays to achieve selectivity during faults ocurring in the electrical network for the 13. The scope of the study can range from an entire utility transmission and distribution.
