35KV 600A Grid Neutral Grounding Resistance Prevent Sudden Shortcircuit
Neutral Grounding Resistors Enclosure is a complete set of equipment specially used for the power generator’s neutral point adapts the high resistance grounding. The arc grounding over-voltage occurs when the Generator main circuits have a high earth fault current. While the generator usually capable of loading low withstand voltage and easier to damage. The generator coil will sever burns if the earth current is too high. The generator neutral grounding resistor is the most popular and safe in the practice by high resistance connecting to the earth.
Key Features:
(1) Material of enclosure: stainless steel or aluminum zinc plate with high corrosion-resistance;
(2) Intellect controlled unit: monitor the unbalanced current, the
resistor plate, the grounding transformer and the enclosure
temperature, It can also transmit the earth fault information to
the controlling room;
(3) Accessories: Switch: ABB, Siemens and Schneider, PLC: Panasonic and Siemens.
