Interval time between upper and lower levels of relay protection

The IEC standard for relay coordination recommends time grading between relays based on fault current magnitude and operating characteristics. For overcurrent protection, a minimum time margin of 0. 5 seconds is often maintained between primary and backup relays. In a power network with multiple protective devices, this coordination. 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. With faster modern circuit breakers and a lower relay overshoot time, 0. Co-ordination procedure Correct overcurrent relay application requires knowledge of the fault current that can flow in each part of the. This calculator evaluates time-current coordination between two protective overcurrent relays — typically a downstream relay closer to the load and an upstream relay closer to the source — at a specified fault current level.
