10.5KV Generator Neutral Point Grounding with 20KVA Transformer

In a power distribution network, the neutral grounding system is usually classified into ungrounded, resistance grounded as well as arc suppression coil grounded. Suitable for single phase grounding fault during operation of generator,when arc occurs to the fault point, the winding insulation damage scope will be further increased causing short circuit between phase or turns.For this reason,high resistance grounding is usually used for neutral point of generator so as to restrict grounding current and prevent damage of overvoltage.At present,this device is widely used for urban power supply system,power plant,metro,metallurgy and petrochemical industry.

Key features of NGR:

1.High-quality stainless stell nickel-chrome alloy or non-metallic materials are used,which have high conductivity,high temperature coefficient and can be durable to the temperature of 1500℃. It's stability is outstanding;

2. It has good weldability performance, between the resistive element sheet-language films, the connecting point use resistance spot welding, non-contact resistance, strong,durable beautiful;

3. Professional protection to aviod the iron core of generator burned down,and reduce damage of iron core of generator's stator winding while grounding.
