Relay protection timing coordination
Step-by-step tutorial on building a time-current coordination chart for a three-level protection system. 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 IEC standard for relay coordination provides clear guidelines and methodologies to ensure that protective relays work in harmony to isolate only the faulty section of the system while keeping the rest. The relay is connected to the circuit to be protected via CTs and VTs according to the required protection function. In order for the relay to operate, it needs to be energized. This energy can be provided by battery sets (mostly) or by the monitored circuit itself. -
