Relay protection current inverse time diagram
The document discusses inverse-time overcurrent protection relays and their time-current curves. It describes the standard inverse, very inverse, extremely inverse, and long time inverse curves defined by IEC 60255 with their corresponding K and E values. Instantaneous relays have operating times usually less than 3 cycles. These relays operate without an intentional time delay, hence they. 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. For ground relays, line to ground faults and max 3Io should be.
