Calculating zero sequence current compensation factor (k0
Adjusting k0 makes the distance calculation more or less sensitive to zero sequence components, which you might care about if you have mutual coupling. Whatever you set K0 to, you
(PDF) Setting Zero-Sequence Compensation Factor in Distance Relays
Based on this analysis, a simple methodology for setting K0 properly is proposed, which is implementable with commercially available relays. The methodology is applied on a test distribution
