The meaning of k in relay protection
The K factor (or zero-sequence compensation factor) adjusts the measured impedance for the phase-to-ground fault loop by accounting for the contribution of zero-sequence currents. Without proper. nterrupting current rating for high-voltage circuit breakers. The paper teaches how the decaying dc component in the asymmetrical fault current affects the breaker, and it explains how the X/R ratio and the relay perating time affect the asymmetrical current breaker rating. Countries using European standards started out using IEC 60750, Item designation in electrotechnology. It does not prevent or delay the type KD relay from tripping on phase-to-phase faults within its protective.
