Switchsync® PWC600
Precision controlled switching of high-voltage circuit breakers for enhanced grid stability
Switchsync PWC600 is an advanced point-on-wave controller engineered for precise controlled switching of high-voltage circuit breakers. It reduces electrical transients, enhances power quality, protects assets, and improves grid performance.
Designed for single-pole operated circuit breakers, Switchsync PWC600 controls each pole independently to operate at the optimal point on wave, minimizing stress on the load, circuit breaker, and power system. This field-proven switching solution integrates intelligent control algorithms with advanced communication protocols, ensuring reliable performance in modern digital substations.
Hitachi Energy's high-voltage circuit breakers are well suited for controlled switching, featuring consistent operating times and steep and stable dynamic dielectric withstand characteristics.
Application
Controlled switching of capacitor banks, shunt reactors, transformers, uncompensated and compensated cables and lines to minimize switching transients.
Designed for single-pole operated circuit breakers with independent pole control.

- Benefits
- Features
Reduce electrical wear and probability of damaging re-ignitions in the circuit breaker.
Prevent nuisance tripping on grid connected equipment due to high inrush currents or grid voltage distortion.
Prevent exposure of circuit breakers and power equipment to excessive switching overvoltages and thereby damage to insulation.
Significantly reduce contact erosion in generator circuit breakers and in turn optimize life cycle costs.
Improve power quality and grid stability.
