Product Description

Switchgear Electrical Power Distribution Control Cubicle
Range of Application:

MRD-FD series generator neutral resistance box is dedicatedly applied to integrated equipment in power station where the generator neutral grounding through high resistance. The mian grade of voltage is from 6KV to 20KV, when one point of stator grounds it could limit grounding current at a very low level and effectively suppress arc grounding transient overvoltage.

NGR Introduce 

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   (Order Note)

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.

Rang Parameters

• 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

Technology Quality 

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

Standard 

Standard unit includes the stainless steel resistor assembly plus all the required insulators, internal connections and hardware installed in a standard safety enclosure. Neutral Grounding Resistor units are completely assembled, prewired, and tested at our facility. For shipping all units are crated for added protection and ease of handling.

Enclosure Options 

•Stainless steel, cold rolled plate construction. Custom paint finish is available.
• Top or side mounted entrance bushing(s).
• Screened covers for indoor applications.
• Support stands for elevating the enclosure above ground.

OPTIONS

Current or potential transformers mounted and prewired at our facility

ON or OFF Load disconnecting switches
