Power Distribution Equipment
Description
1. Brief Introduction
1.1 Definition
MRD-NP Transformer Neutral Discharging Gap is complete electrical equipment consisting of disconnecting switch, lightning arrestor, discharging gap and CT.
1.2 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 MRD-NP Transformer Discharging Gap to protect neutral of transformer so as to prevent accidents from happening.
