Neutral Grounding Resistors

Features

1.Inserting an Neutral Grounding Resistor between neutral and ground in series.

Proper selection of the resistance value of the connected resistor can not only discharge the energy of the second half wave of the single phase grounding arc, so as to reduce the possibility of arc reignition,and suppress the radiation value of grid overvoltage, but also improve the sensitivity of the relay protection device to act on tripping,so as to effectively protect the normal operation of the system.

2.Nominal Value: 0.1 Ohm-1500 Ohm(customized as required).

3.Tolerance:±5%

4.Voltage Scope:380V-69KV(customized as required).

5.Allowable flow time: 10s, 30s, 60s and 10min continuous operation are optional.

6.Strong pertinence,stable resistance value,resistance high temperature and resistance strong impact,to ensure the safe operation of power system, power supply reliability and user power safety.

Applications

Widely used in power plant power consumption system,substation power supply system and industrial and mining enterprise power distribution system to realize the zero sequence current detection function by inserting neutral grounding resistor between neutral and ground among these grids ,so as to ensure the normal operation mode of the system.
