What is the characteristic of the Inverse Time Overcurrent Relay?
A. The relay will work. When detecting the measured impedance is less than the set value then relay will work immediately at the beginning. and the faster the operation is, if the impedance is less.
B. The relay will work. When detecting that the Fault current exceeds the current value Then relay will work immediately at the beginning. And the faster the operation is, if the current is less
C. The relay will work. When detecting that the Fault current exceeds the current value, and has a variable working time according to the amount of faulty currents
D. The relay will work. When detecting that the Fault current exceeds the current value and there is a time to work as an inversely proportional to the amount of current
