11.5 KV CAPACITOR BANK

The metal enclosed medium voltage capacitor banks are designed for indoor and outdoor application in industrial and utility power systems requiring power factor correction, harmonic filtering as per IEC compliances and can increase the system capacity.

The metal-enclosed capacitor banks are designed at 11.5 kV rated voltage, which are factory assembled and type- tested outdoor panels.

It provides a one-step solution for maintaining the power quality in medium voltage networks and comprises of premium range of primary and secondary components, including world-class, highly reliable capacitors.

Capacitor banks improve the power quality by compensating reactive power, improving power factor, or passively mitigating harmonics.

The system can be either configured as fixed or switched, with the switched bank consisting of single or multiple steps, automatically controlled to improve power factor.

The design consists of a compact modular enclosure that combines primary components with secondary control and protection equipment.

Sheet metal enclosures and covers painted with epoxy or polyester powder paint.

Canopy design with pressure relief flap.

  • Advanced reactive power compensation for dynamic or fixed loads on polluted networks.
  • Electrical and mechanical interlocks for safe accessibility.
  • Cabinet protection class up to IP55.
  • Enclosed design providing full protection of live parts.
  • Isolated control compartments.
  • Internally or Externally fused capacitors.
  • Multi-stepped, and automatically controlled.
  • All cable termination at the bottom with aluminum gland plates.
  • Modular cabinet design for easy transportation.
