Practical Electrical Network Automation and …

Owing to natural system unbalances (leakage reactance, inrush currents to transformers and motors, etc) and CT and relay inaccuracies, the earth fault setting can seldom be lower than 10–20% of full load current, depending on system conditions, otherwise stability of the relay is compromised, and ‘nuisance tripping’ may occur.
