Stainless Steel High Power Adjustable Neutral Grounding Resistor
Product overview and application:
It is suitable for the single-phase earth fault when the generator is running. When the arc is grounded, it will further expand the insulation damage range of the stator winding, resulting in inter-phase or inter-turn short circuit. Usually the generator neutral point with high impedance grounding.
Features of the neutral grouding resistor:
1. the product is made of high quality stainless steel nickel-chromium alloy or non-metallic material, its high
conductivity, high temperature coefficient, the maximum resistance of 1600 ℃ high temperature, good stability.
2. cabinet grounding transformer using dry-type transformers, large capacity, impact resistance.
3. professional protection, to avoid burning the generator core, to reduce the generator stator winding ground damage when the core;
4. can be configured epoxy cast dry ground transformer, zero sequence ct, single-phase isolation switch, resistor on-line monitoring device, heater and temperature and humidity control, etc., can effectively monitor the ground fault current, voltage, and provide switch and alarm contacts.
