1.Purpose:

This product is used in 6KV~66KV 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 20%-100% rated current.

2.2  High-voltage grounding and line-selection modules can be embedded.

2.3  RS232 and RS485 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 35KV,66KV system, the grounding transformer is not needed.

3.2 Arc-suppression coil(dry type or oil immersed)

 3.3 Damping resistor

 3.4 Control cabinet

3.5 PT cabinet
