Ampcontrol Equipments Neutral Grounding Resistors

features :
neutral grounding resistors are used in star connected systems to protect the transformer / alternator from severe damage caused in event of an earth fault.

we manufacture neutral grounding resistors for all current ratings upto 3000a and for a voltage range from 230v to 36kv.

the resistors can be designed in cast iron grid, rod formed grid, wire wound and punched grid form.

advantages of using a neutral grounding resistor:
• reduced operation and
• maintenance expenses.
• fast isolation of the original fault.
• reduced transient over voltages.
• reduced physical damage on the
• equipment at fault.
• simplification of ground fault location.
• increased life and protection of
• transformers, generators and
• related equipment.
• reduced frequency of faults.
• improved service reliability.
• increased protection in the use of lightning arresters.
• increased safety for personnel
