35KV 340A Neutral Grounding Resistor for Wind power Electric Field

Brief introduction: Resistance grounding has become more widely used for the urban power grid with cables.However,for the grid with"△"connection for transformer winding,when the neutral point needs to be grounded,"Z"type transformer shall be added and then,grounding resistor is installed to the neutral point of "Z"type transformer to prevent the damage to the HV canles and other electrical equipment by sudden short circuit and intermittent arc overvoltage and increase the reliability of the power system operation.

Main features:

If our neutral grounding resistor is installed, the ground fault current will be reduced significantly when
compared to ungrounded system. At the same time, the voltage increase of un-faulted phase is also lowered
obviously, and the zero sequence voltage is only half the value of ungrounded system when single phase
ground fault occurs.
In this regard, our neutral grounding resistor could reduce transient overvoltage and eliminate resonance
overvoltage when a ground fault of one phase takes place, and a simple protective relay can locate and clear the fault. So, this power resistor is highly recommended to protect electrical system and corresponding
equipment.
