6.9kv Earthing Resistor Panel

With our sound facilities, we are engaged in manufacturing, exporting and trading a massive gamut of 6.9kv Earthing Resistor Panel in Baoding, Hebei, China. Neutral Grounding Resistors are used for resistance grounding of industrial power system.They are generally connected between ground and neutral of transformers, generators and grounding transformers. Neutral Grounding resistors are used in order to limit maximum fault current to a value which will not damage the equipment in the power system, yet allow sufficient flow of fault currents with high resistance Neutral Grounding Resistors, earth short circuit current can be extremely reduced. As a result of this fact, protection divicesmay not sence the fault . Therefore, it is the most common application to limit single phase fault currents with low resistance Neutral Grounding Resistors to approximately rated current to transformer and / or generator.

1. Advantages of using a neutral grounding resistor:
a c Reduced operation and
a c Maintenance expenses.
a c Fast isolation of the original fault.
a c Reduced transient over voltages.
a c Reduced physical damage on the
a c Equipment at fault.
a c Simplification of ground fault location.
a c Increased life and protection of
a c Transformers, generators and
a c Related equipment.
a c Reduced frequency of faults.
a c Improved service reliability.
a c Increased protection in the use of lightning arresters.
a c Increased safety
