Sell loop tuning 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.
