Function 

Most neutral of 110KV/220KV power networks are not grounded. In such systems, the neutral is easy to get overvoltage if struck by lightning or short-circuited by single-phase grounding fault. Besides most transformers are uniform insulated. This will greatly threaten insulation of neutral point. Therefore, we use WF-ZJB Transformer Discharging Gap to protect neutral of transformer so as to prevent accidents from happening.
