Distance Relay k0 question
Distance Relay k0 question
(OP)
Hi
Earthfault compensation factor k0 = (Z0-Z1)/3*Z1. Also Z0 = Z1 + 3Ze where Ze = impedance of return path whether it be via general mass of earth, OHEW or a combination of both. For overhead transmission lines is it possible that X0/R0 > X1/R1? which leads to the question can k0 have a positive angle? I have ever only seen it being negative.
Thanks.
