WebApr 10, 2024 · The plug setting multiplier of a relay is defined as the ratio of secondary fault current to the pick up current. PSM = Secondary fault current/Relay current setting. Pick up current = (Rated secondary current in CT) x (Current setting) Calculation: Given that, Current setting = 150% = 1.5. Relay CT ratio = 300/5. Rated secondary current = 5 A WebThe total relay operating time= Plug setting Multiplier time (Which is available in the relay) * Time Multiplier Setting. Take an example of the above mentioned, in this, consider relay TMS is 10% and PSM=8.. Hence the timing for PSM 8, Time =2 sec…then the relay operating time is 2 * 10% = 0.02sec.

WebJan 22, 2024 · o Pickup Setting (TAP or 51P1P) The Time Dial setting (TD) decides the operating times of the overcurrent relay while the Pickup Current ( TAP or 51P1P) decides the current required for the relay to pick-up (trip). The multiple of pickup (M) is also called Multiple of Tap. The name “Tap” comes from the electromechanical overcurrent relays. newman print jamestown nd
