3) The relay settings for percentage differential
protection scheme for generator are as under.
(1) Pick-up current 0.05 A
(ii) Slope = 10 %
(iii) CT ratio = 400/1
A high resistance single line-to-ground external fault occurs
when the generator is supplying the power to the load. The
magnitude of current through CT1 and CT2 is 400 A and 375 A,
respectively. Determine whether the relay will operate in case
of the given situation.
Relay will operate
Relay will not operate
On the verge of operation
Data is insufficient
