Part-III

TECHNICAL SPECIFICATION FOR

NEUTRAL GROUNDING RESISTOR






Part-III


FOR NEUTRAL GROUNDING RESISTOR

1.00.00 DESIGN CRITERIA 1.01.00 The Neutral Grounding Resistor shall be used for non-effective grounding of 11000 V

and 3300 V system of the plant.

NGR shall be connected between the 11000 V star connected winding neutral point of station transformers, unit transformers and other HT auxiliary transformers and earth.

NGR shall also be connected between the 3300 V star connected winding neutral point of HT auxiliary transformers and earth.

1.02.00 Neutral Grounding Resistor shall be used to limit the magnitude of earth fault current so

that damage of electrical equipment is reduced, safety of personnel is increased and sensitive, selective earth fault protection can be provided.

1.03.00 The NGR shall be installed in dust prone, hot, humid and tropical atmosphere. All

equipment, accessories and wiring shall be provided with tropical finish to prevent fungus growth.

1.04.00 The rated time for the earth fault current or specified thermal current shall be 10

seconds. 1.05.00 The Bidder shall quote for neutral grounding resistor with final temperature as per
