Voltage phase sequence protector (voltage monitor) is a kind of protection voltage misphase (fault identification protection, automatic phase sequence fault elimination), phase failure, over voltage, under voltage, voltage imbalance
Overvoltage: the voltage (Umax-Ue)/Ue*100% required to discharge the ions on the electrode beyond the equilibrium potential of the electrode;
Undervoltage: the voltage required to discharge ions on the electrode below the equilibrium potential of the electrode (Umin-Ue) / Ue * 100%;
