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. 1.732
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
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
Temperature Rise Allowed: Normally Temperature rise is restricted to 375 deg.c. above ambient temperature as per BS-587
Cabling or termination : Suitable arrangement and clearance is provided for termination of cable, flats or bus duct as per requirement with removable gland plate
Construction: NGR include resistor assembly, plus required insulators, internal connections and hardware etc
