Ior detection method Earth leakage direction relay
Hikari Shoko Co., Ltd.
About This Product
Earth leakage relay that can avoid overloading in low-voltage direct grounding circuits
The Ior detection method separates and calculates the resistance leakage current according to the circuit configuration based on the zero-sequence current detected by ZCT and the ground-to-ground voltage input from the L-E terminal. The calculation method of the Ior detection method differs depending on the circuit type, so it is necessary to set the LIG-12's "Cable path setting" switch according to the circuit type.
■Features
・Earth leakage direction relay for low voltage direct grounding circuit.
・The earth leakage monitoring section has a directional function to prevent accidents.
