◎The power supply has obvious interference to other equipment (interference, overvoltage)
◎Power phase-to-phase voltage imbalance > 1.8% of rated voltage
◎Very low impedance line (power transformer is more than 10 times the rated value of the inverter)
◎Large number of frequency converters installed on one line to reduce line current
◎Correct the capacitance or power factor correction unit using cosΦ (power factor).
