| Abstract: | The risk of operation of 10 kV PT was analyzed.Hence common operation rules to avoid the risk were presented.Based on risk analysis of 10 kV PT,several possible risks due to the operation are discussed,such as relay protection of the main transformer, energy measurement,zero sequence impedance of 10 kV system,so an improved connection way and operation method is proposed.By this way,the operation could become more reliable and quickly,hence the reliability of utility's power supply could also be improved. |
