Plug Setting Of Relay at Tristan Sloane blog

Plug Setting Of Relay. Psm = i (pickup)/ i (rated. The current plug settings usually range from 50% to 200% in steps of 25% for overcurrent relays and 10% to 70% in steps of 10% for earth leakage relays. The generic inverse definite minimum time (idmt) time current curve calculator will allow you to not only produce curves for standard iec and ieee relay characteristics but will give a trip. The plug position is set at 2.5 times or 250% of the rated ct current. In this post we will focus on the concept and implementation of plug setting multiplier and time setting multiplier for electromechanical relays. Current setting (plug setting) is either be given in ampere or as percentages of rated current. The ratio of the fault current to the relay’s pickup current, critical for relay operation. As we know that an electromechanical relay has a coil which when energized, operates the relay to have contact changeover. This will give the value of the pickup current. I (pick up)= plug position (psm) * rated ct current. Adjusts the relay’s operating time by setting how quickly the relay contacts close. The desired current setting is obtained by inserting a. Plug setting (current setting) 10%, time dial (tms) setting 0.07 and the instantaneous or high fault settings for o/c and e/f are set to 300% for both.
