Model: KgN
Neutral Grounding Resistor
The KOBN Neutral Grounding Resistor (NGR) – Model KgN is engineered for reliable fault current control and enhanced transformer protection in medium- and high-voltage power systems. With a rated voltage of 11kV, current capacity of 300A, and stainless steel 304 resistor elements, it provides precise resistance (21.1Ω ±5%) and withstands short-time fault conditions up to 30 seconds. Housed in a hot-dip galvanized, IP23-protected enclosure with RAL7035 finish, it ensures durability against harsh indoor environments. Designed to meet IEC and DL/T 780-2001 standards, this NGR delivers stable performance, extended equipment life, and safe grounding for substations, industrial plants, and distribution networks.
