Professional Experience
Baoding Mingrui Optoelectronics Technology Co., Ltd is the professional manufacture of resistor and transformer.We are engaged in the manufacturing and supplying of Neutral Earthing Resistors, which are used to limit the current flow during an earthing fault on an alternative current distribution system. The Neutral grounding resistor is applicable to 6~35kv power distribution grid of cable lines . it be widely applies to transformer substation.
These Resistors are connected amid the neutral position of a Generator and Earth or Transformer and Earth. They are extensively used in miming, industrial installations and power distribution. These Resistors are designed to operate in harmful working conditions and environmental changes. Our products are highly appreciated for their reliability and durability.

Additional Information
pplication: Neutral grounding resistor to protect power transformers and generators from damaging currents in the event of earth fault.
Neutral grounding resistors are designed to detect and limit fault currents within a three phase power transformer or generator.
The resistor will be connected between the neutral point of the symetrical three phase windings and ground.
Associated to measuring apparatus, it will allow detection and control of defaults.
We can use different protection level (IP level) for NGR such as IP23, IP 54 & IP 55.
