Stainless Steel Neutral Earthing Resistor Customized Load Bank and Application:
Neutral Grouding resistor systems protect power transformers and generators from damaging fault currents.
Grouding of the neutral limits the ground fault current to a high level (typically 50 amps or more) in order to operate protective fault clearing relays and current transformers. These devices are then able to quickly clear the fault, usually within a few seconds. The importance of this fast response time is that it:
* Limits damage to equipment
* Prevents additional faults from occurring
* Provides safety for personnel
* Localizes the fault
* UL Listed
* Seismic Zone 4 Certifications and type tests also available
Product Features

Advantages of Fullde Neutral Grounding Resistor:
1. The standard size of the switchgear design is beautiful, and the overall fit of the customer's field equipment.
2. Adopt high-quality nickel-chromium alloy resistance sheet, high power density, low temperature coefficient, good corrosion resistance.
3. Non-inductive processing technology to prevent eddy current inside the resistor.
4. Configure the transformer recorder, etc., the resistor can record the running status and provide remote monitoring function.
5. The resistance core adopts double insulation design to meet the fault current impact and maintain the insulation performance of the resistor.
