Part-III
TECHNICAL SPECIFICATION
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
allowable limit due to the specified current for specified time. 1.06.00 The resistor unit shall be air-cooled type suitable for installation at outdoor locations. 1.07.00 Rating and requirements of NGR are indicated under Annexure-A. 2.00.00 SPECIFIC REQUIREMENTS 2.01.00 Resistor 2.01.01 The resistor element shall be made of non-aging stainless steel or equivalent corrosion
resistant material having high electrical resistivity and low temperature co-efficient of resistant. The NGR shall have temperature limited to the maximum allowable temperature for the material offered considering the air ambient temperature at site as mentioned earlier.
2.01.02 The resistor unit shall consist of a no. of elements. All the elements shall be mounted
inside the cubicle so as to ensure ease of inspection and replacement of individual element. The resistors shall be edge-wound type.
2.01.03 Each resistor element shall possess a balanced combination of both mechanical and
electrical properties over the entire intended operating temperature range without any harmful effect on the elements and their accessories.
2.01.04 All the resistor elements constituting the NGR shall be assembled and supported inside
the cubicle in such a way that no distortion or breakage shall occur during the passage of through fault current to earth.
