Design and Realization of Intelligent Phase-controlled System for Permanent Magnetic Actuator of AC Contactor [PDF]

open access: yesE3S Web of Conferences, 2020
When the AC contactor switches the capacitor bank, the phase angle of the power grid is random, so the electromagnetic transient process will generate large inrush current and overvoltage, causing large disturbance to the power system.
