| Abstract: | The explosive reasons for two 10 kV electromagnetic type voltage transformers (TV) were analyzed. The schemes for 2 substations to adopt the switch scheme and 4 TV scheme respectively were put forward. The paper elaborated the common over voltage type in medium voltage power network-the forming reason and developing mechanism for operating over voltage and ferro-resonance over voltage, and some kinds of effective solving scheme were presented. |
