| The neutral grounding resistor is a current limiting electrical protection device connected between the neutral points of the generator and transformer. In case of failure in the power network, the neutral voltage will produce an offset, especially in a grid system of cables whose capacitive earth current is high, arc grounding overvoltage will be produced when the current is greater than the specified value so that the non-fault phase-to-ground voltage will be greatly increased, the equipment insulation will be damaged, thus causing short circuit of earthing at two or more points and power outage. | |||||||||
Product Feature
Product Introduction
The neutral grounding resistor is a current limiting electrical protection device connected between the neutral points of the generator and transformer. In case of failure in the power network, the neutral voltage will produce an offset, especially in a grid system of cables whose capacitive earth current is high, arc grounding overvoltage will be produced when the current is greater than the specified value so that the non-fault phase-to-ground voltage will be greatly increased, the equipment insulation will be damaged, thus causing short circuit of earthing at two or more points and power outage.
Product Application
The device is suitable for use in the dead earthed neutral system of a distribution network of 0.4-110kV voltage level.
Applicable Standards
GB/T5729-1994
