Acutran Neutral Grounding Reactors are used in Industrial applications for grounding wye connected generators. They are usually connected between the neutral and the ground to control the line-to-ground fault current. Acutran’s Neutral Grounding Reactor is a Current Limiting Reactor which limits the fault current to a level that can accommodate the protective relays and prevent fault current from damaging your equipment.
The advantage of a NGR:
- Reduced over-voltages.
- Reduced equipment damage.
- Isolation of faulted circuit and quicker location identification.
- Increased protection of transformers, generators and auxiliary equipment.
- Reduced operation/maintenance expense.
- Increase safety.
- Improved reliability.
- Reduced frequency of faults.
Which to choose – Reactor or Resistor?
Acutran makes systems using both reactors and resistors. In general, if the customer is looking to significantly restrict the fault current using actual resistance, then a resistor is the way to go. However, if the system as a high tolerance to large fault currents of 500A or more then a reactor is more appropriate. Normally, in the end a reactor is more cost efficient.
