Neutral Grounding Resistor

Range of application

Neutral earthing resistors are mainly applied to the electric power system under 110KV. One is the electric power distribution system which is composed by cable lines, with big fault capacitance and current (single-phase earthing). The other is the electric power system for electric power plant whose capacitance and current are little but to avoid the resonance .The former system is mostly low-resistance earthing , and later is high-resistance earthing. Therefore, neutral earthing resistors are especially suitable for urban electric networks , large industry garden, electric power plant, maritime electric power distribution system and large chemical enterprises,etc
