In Brief
FUNCTION
Neutral Grounding Resistors are used to protect power transformers, power generators and other
Associated equipment in your power systems against 50/60 Hz faults (short circuit) and transient
Phenomena (lightning).
SPECIFICATIONS
There are six parameters needed to specify the neutral grounding resistor.
1. Rated voltage line to neutral or system voltage.
2. Rated fault current.
3. Rated "duration time" of the line to neutral voltage not exceeding the allowable temperature rise.
4. Rated Resistance.
5. Application environment, indoor or outdoor.
6. Enclosure material, ss plate or normal cold rolled sheet.
RANGE
Rated current: From 1 AMP to 2000 A
Rated voltage: From 0.4 to 35kV
Rated Resistance: From 1 ohm to 2000 ohm
Rated time: 1 sec to continuous time rating
TESTING AND QUALITY
All Mingrui Neutral Grounding Resistors are designed, rated, manufactured and tested in strict compliance
With IEEE-32. Routine tests performed on each Neutral Grounding Resistor are measurement of resistance,
High voltage power frequency, insulation measurement, aspect verification, dimensional control. Mingrui's
Internal quality system has been developed and certified under ISO 9001 quality system
CONSTRUCTION
