Loss-of-Potential, CCVT Transient Detection, Load-Encroachment, and Directional Element Logic
Loss-of-Potential Logic
Setting ELOP = N
If setting ELOP = N, the loss-of-potential logic still operates (Relay Word bit
LOP asserts to logical 1 for a loss-of-potential condition) but does not disable
any voltage-polarized directional elements or any distance elements (as occurs
with ELOP = Y or Y1), nor does it enable overcurrent elements set direction
forward (as occurs with ELOP = Y).
