Point-on-Wave vacuum switch PS+ SynC
The PS+ SynC is Hitachi Energy’s next-generation, digitally enabled vacuum switch developed to provide transient free, smooth, and reliable operation. Incorporating best-in-class vacuum technology, the PS+ SynC reduces system stress and end user life cycle costs, while improving network power quality.
Built upon over 20 years’ experience with the proven PS switch range platform, the PS+ SynC combines Hitachi Energy's time-tested design reliability with modern, state-of-the-art digital capability. This combination provides valuable performance insights with high operational reliability to users.
All PS+ SynC units are delivered ready to install and be “plug-and-play” capable either as a packaged solution or standalone product, fully tested and calibrated from the factory minimising installation and commissioning time on site.
Applications
Used for capacitor switching in:
- Pole-mounted capacitor banks
- Open rack capacitor banks (medium voltage)
- Metal-enclosed capacitor banks
Apart from Hitachi Energy’s capacitor banks, PS+ SynC vacuum switches can also be used in OEM solutions, integrated with third-party components and controllers.
