arc-suppression coil

详情

1.Purpose:
This product is used in 6KV~*6KV systems whose neutral point is ungrounded to limit the arcing currents during ground faults.

 2.Features: 
2.1  Able to achieve the full range of adjustment within *0%***0% rated current.
2.2  High-voltage grounding and line-selection modules can be embedded.
2.3  RS**2 and RS**5 communications interfaces are equipped.
2.4  Able to display alarm data.
2.5  Able to print the grounding information.

 3.Structure:
3.1 Zigzag connection grounding transformer(dry type or oil immersed). If there is a line connecting the neutral point of the transformer in *5KV,*6KV system, the grounding transformer is not needed.
3.2 Arc-suppression coil(dry type or oil immersed)
3.3 Damping resistor
