Single phase distribution transformer

Prototype Development of 20 kV Single-Phase Distribution Transformer

1. Design of 20 kV Single - phase Distribution Transformer 20 kV distribution systems usually adopt cable lines or mixed cable - overhead line networks, and the neutral point is mostly grounded through a small resistance. When a single - phase grounding occurs, there will be no problem that the phas
