Main technical performance index
1.Capacitance deviation
1.1The difference between the actual capacitance and the rated capacitance of the device is within the range of 0- +5% of the rated capacitance. The standard is higher than other factories
1.2The ratio of the maximum to the minimum capacitance between any two line terminals of the device shall not exceed 1.02.
2.Inductance deviation
2.1Under rated current, the allowable deviation of reactance value is 0~+5%.
2.2The reactance value of each phase shall not exceed ± 2% of the average value of three phases.
