A point-on-wave controller is a high-speed, microprocessor-based relay that synchronizes the opening or closing of an AC circuit breaker to a preselected instant on the voltage waveform. By triggering at the optimal phase angle, it minimizes switching transients and inrush currents
Transformer energization to limit magnetizing inrush
Shunt reactor switching for reactive power control
Capacitor bank operations to suppress voltage transients and Inrush Current
Transmission line switching to enhance grid stability
