Specification of 20 Kv 300 Ampere 40 Ohm Neutral Earting Resistor

NEUTRAL GROUNDING RESISTORS (NGR) 20 Kv 300 Ampere 40 Ohm


TECHNICAL SPECIFICATIONS

20 kV 300 Ampere 40 Ohm, 10 second

IP 23 (max IP 54)

Resistor Material: Grid

Enclosure: custom, Galvanize Steel, Mild Steel, Stainless Steel

Including NCT


ENCLOSURE

The frame enclosure must be made of structural steel, all corners are welded, or bolted with stainless-steel hardware. The top of the enclosure should be solid, slightly outward and at a slight angle. An eyebolt must be attached for lifting purposes. The front of the enclosure must be ventilated with holes in the form of a grille. The sides of the four sides must be bolted. Nameplate permanently attached to either side shall show the complete manufacturing and rating.


RESISTOR

• Resistive elements must be low temperature coefficient. The stainless steel mass grade resistors are sufficient to withstand the prescribed duty.

• Resistors must be installed in a stainless steel support frame.

• The entire resistor assembly must be mounted on an insulator appropriate to the system voltage.

• All resistor terminals and interconnections between resistor units must be stainless-steel using stainless-steel hardware including lock washers.
