Medium voltage metal enclosed capacitor banks built to improve performance and efficiency of electrical systems

Our medium-voltage metal-enclosed power capacitor banks are cost-effective, flexible, predictable, and easy to maintain series of products. Our capacitor banks are custom built to customer requirements and are shipped factory tested, assembled, and ready for interconnection. Enclosures contain all switching, protection, safety features, and control. When compared to an “open-rack” capacitor bank, they save you money as they are easier and faster to install, commission, maintain, and take up less space.

Powerside medium-voltage metal-enclosed harmonic filter banks are designed for medium voltage power factor correction, voltage support, mitigation from harmonic distortion and prevention from risks of resonance. The harmonic filter banks are configurable as fixed or automatic with 1 or more stages at nominal voltages from 2.4kV to 35kV. Available filter types include C-type, High-Pass, detuned, single-tuned, and multi-tuned.

Features

  • Fixed, single-step and multi-step capacitor and filter banks
  • Indoor or outdoor environment, and made with cold-rolled, galvanized or stainless steel
  • Low voltage protection and control equipment in a separate and easily accessible compartment
  • Medium voltage incoming section and stages in separate compartments for ease of access and maintenance
  • Programmed to provide the site-specific needs for power factor, harmonic and voltage mitigation
  • Choice of between classic interface (pushbuttons, switches and pilot lights), or Smart Control Interface (SCI+) with touch screen
  • Smart Control Interface (SCI+) allows for easy control with complete status of the bank, history of events, locally via the HMI or remotely with multiple, password-protected levels of access
  • Factory pre-assembled, tested and ready for fast installation and interconnection

Benefits

  • Free up the power capacity of the facility
  • Arc protection for safety of personnel and operation
  • Simpler engineering, project management installation than open-rack design
  • Improve the voltage profile and power factor
  • Reduce the apparent current and system loses
  • Increases the lifetime of transformers, motors and others by eliminating harmonic currents
  • Provide reactive energy required by inductive loads
  • Avoid penalties due to poor power factor.
  • Reduces GHG emissions

Applications

PowerMVar and SynchroMVar are designed to provide power factor compensation and harmonic mitigation for any environment from low harmonics requiring fixed compensation to high harmonics requiring highly dynamic compensation.
