Power Distribution Room Relay Protection Coordination Scheme
Step-by-step tutorial on building a time-current coordination chart for a three-level protection system. Determining the fault clearance time and coordinating upstream electrical pro-tection. Protection relay coordination is the practice of setting protective devices so that the device closest to a fault trips first, limiting the outage to the smallest possible section of the distribution system. Relay protection is often misunderstood as a. 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.
