Solved 2 C04 A In An Oc Relay If The Fault Current Is Chegg Question: in an oc relay, if the fault current is 200 a, the relay setting is 50% and ct ratio is 400:5, find the plug setting multiplier. figure 1 shows percentage differential relay applied to the protection of an alternator winding. The plug setting multiplier is used only in electromagnetic relays not in numerical relays. the operating times of the relay operation are depending upon the psm.
Idmtl Overcurrent Earth Fault Relay Rea200n Munhean Munhean However, when the prospective fault current varies substantially with the location of the fault, it is possible to make use of this fact by employing both current and time grading to improve the overall performance of the relay. Major disadvantage of such type of grading is applicable only if there is large difference in magnitude of fault current between the two overcurrent relay locations, which is almost impossible to achieve. Calculate overcurrent and inverse time relay settings accurately with our ieee and iec standard based selection calculator for optimal protection coordination. In an oc relay, if the fault current is 200 a, the relay setting is 50 a, and the ct ratio is 400.5, find the plug setting multiplier. figure shows a percentage differential relay applied for the protection of an alternator winding. the relay has a minimum pickup of 0.1 a and a slope of 10%.
