Product Profile of Industrial Purpose Neutral Grounding Resistors

Industrial Purpose Neutral Grounding Resistors are connected between the neutral & the earth so that it will limit the earth fault current to a safe value. These Neutral Grounding Resistors are available in a range of up to 66Kv. These Neutral Grounding Resistors can operate in a condition of no earth fault where continuous current from 5 % to 10 % of full load current range, may pass through the resistor due to system unbalance. Industrial Purpose Neutral Grounding Resistors can also function in earth fault condition where restricted fault current passes through the resistor protecting the system till automatic protection takes place.

Key Features of Industrial Purpose Neutral Grounding Resistors

• Connected between the neutral & the earth so that it will limit the earth fault current to a safe value (Normally full load current of the generator, transformer, etc. thereby protecting the transformer, generator system)
• No Earth Fault: Continuous current (5 % to 10 % of full load current) may pass through the resistor due to system unbalance.
• Earth Fault Condition: Restricted fault current passes through the resistor protecting the system till automatic protection takes place. The earth pressure (Rated Voltage) is absorbed by the resistor protecting the winding etc.
