Neutral grounding resistors
Neutral Grounding Resistors (NGR) or Neutral Earthing Resistors (NER) are designed to detect and limit fault currents within a three-phase power transformer or generator.
The resistor is connected between the neutral point of the symetrical three-phase windings and the ground.
Associated to measuring apparatus, it will allow detection and control of defaults.
Neutral grounding resistors are defined through 3 main parameters :
- Network voltage (Un) or rated voltage (Ur = Un / √3)
- Fault current (In)
- Rated fault duration
Neutral Grounding Resistors are designed as per your requirements, and additional components such as current transformers, voltage transformers, disconnectors, etc. can be included in the resistor.
