Applications
- Local reactive compensation — compensation applied close to the load rather than only at a central point.
- High voltage distribution systems — systems where reactive power needs to be compensated at high voltage.
- Installations needing individual capacitor protection — where each capacitor is protected by its own high-voltage expulsion fuse.
- Sites requiring operator safety interlocking — installations where forced interlocking of live parts is a requirement.
Installation Conditions
- The device uses a cabinet-type structure, so it is installed as a complete cabinet and is intended to be convenient to use and maintain.
- The forced interlocking safety device for the high-voltage live parts must be correctly set, as personal safety depends on it.
- Each capacitor is protected by a high-voltage expulsion fuse, so the fuses must be accessible for checking and replacement.
- Confirm the dynamic and thermal stability requirements of the installation point against the device rating.
How to Select
- Rated voltage of the high voltage system being compensated.
- The total reactive power to be compensated locally.
- The number and rating of capacitors, given that each is protected by an individual expulsion fuse.
- The dynamic and thermal stability required at the installation point.
- Whether the cabinet arrangement and maintenance access suit the available space.
