Each phase voltage group includes a sampling value of a phase voltage of each phase wire by measuring each phase wire. Unbalance rates between the banks are based on the groups of sampling values. The unbalance rate is a ratio between capacitances of every two phase wires. The isolated neutral system working voltage is based on the unbalance rates. The unbalance rates between banks are based on the sampling values measured in real time. The working voltage is based on the unbalance rates, permitting subsequent operations to be accurately performed.Type: ApplicationFiled: May 20, 2022Publication date: July 18, 2024Inventors: Hai Tao Lian, Fei Wang, Hui Nan Mei, Liang Shen
