Rod Grid Type Neutral Grounding Resistor

Product Description

Known for its smooth functioning and wide application areas, our range of Neutral Grounding Resistors is extensively demanded and availed by our clients at the most reasonable and competitive prices. Besides, our expert team give special care to the quality aspects of our offered products.Feature of Neutral Grounding Resistors : Robust constructionCompact designDurable Specifications: Rated Voltage : For neutral grounding or earthing resistor rated voltage means line- to neutral voltage i.e. System Voltage divided by root 3 i.e. 1.732Rated Current : Means Initial current that will flow through resistor when it is cold. Normally Full load current value is same as Rated currentTime Rating : It is length of time for which NGR must tolerate rated voltageShort Time Rating : Normally it is 10 sec. or 30 sec. or 60 sec. depending on design parameters of protection systemContinuous Rating : It is normally 10 % of full load current for healthy system neutral grounding resistor to be designed for continuous rating of 5 % to 10 % of full load currentTemperature Rise Allowed: Normally Temperature rise is restricted to 375 deg.c. above ambient temperature as per BS-587Cabling or termination : Suitable arrangement and clearance is provided for termination of cable, flats or bus duct as per requirement with removable gland plateConstruction: NGR include resistor assembly, plus required insulators, internal connections and hardware etc.Specification Usage/Application Electrical Industry Material SS 304,SS 430,SS 410,Cast iron,Fe-Cr-Al (SS-406) Brand National Resistors Current 1A - 1000A Generator Voltage 415 V- 33 KV Frequency 50 Hz
