Also having material for enclosure (protection class as per IS-12063)
Accessories Require such as space heater, current transformer, isolating switch on load & off load, manually or motorised
Rated Voltage : For neutral grounding / earthing resistor rated voltage means line- to neutral voltage i.e. System Voltage divided by root3 i.e. 1.732.
Rated Current : Means Initial current that will flow through resistor when it is cold. Normally Full load current value is same as Rated current.
Time Rating : It is length of time for which NGR must tolerate rated voltage.
Short Time Rating : Normally it is 10 sec. or 30 sec. or 60 sec. depending on design parameters of protection system. IS-3043 recommends 30 sec. rating.
Continuous 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 current (if required).
Material of Resistance Element : We offer resistor elements made from any stainless steel or FeCrAl or Cu-Ni or Ni-Cr or any other resistance material as per requirement. Normally formed stainless steel element are best and economical for NGRS.
Temperature Rise Allowed: Normally Temperature rise is restricted to 375 deg.c. above ambient temperature as per BS-587. It can be 760 deg.c. as per IEEE-32. It can be offered of any other temperature rise as per customer's requirement.
Construction: NGR include resistor assembly, plus required insulators, internal connections and hardware etc.
Cabling / Termination : Suitable arrangement and clearance is provided for termination of cable, flats or bus duct as per requirement with undrilled removable gland plate.
