Reactive power compensation

Reactive power compensation

Price: Please contact

The combined reactive power compensation banks of the OPTIM SVGm range are suitable for reactive power compensation in any installation where the use of rejection filters is required due to the presence of harmonics in the network, but especially in those where, due to the compensation requirements, using a conventional capacitor bank based on steps operated by contactors does not guarantee proper power factor correction that rules out the possibility of being penalized for excess reactive power consumption.
Installations where part of the total power of the compensation device has to respond quickly.
Installations where the addition of a self-supply system based on photovoltaics varies the demand for active power from the network such that a bank with steps does not cover the compensation needs, or those where at certain times, there is excess capacitive power, which is also subject to penalization.

SVGm cabinet-type static var generators are the most accurate power factor correction solution in both unbalanced three-phase systems and installations with inductive and capacitive reactive power. They can be used in three-phase industrial, commercial or service installations, and they are not affected by the installation's harmonics. Much safer device with minimal maintenance. This product range features rack assembly in standard cabinets, designed to simplify installation.

The implemented characteristics and functions are as follows:

  • Power factor correction (inductive/capacitive) from 30 to 100 kvar (3W) and 20 to 69 kvar (4W) per cabinet.
  • The 100 kvar (3W) and 69 kvar (4W) rack-type module's compact dimensions make it easy to install in standard cabinets.
  • Multi-range voltage and frequency (50/60 Hz).
  • Harmonic current immunity.
  • Cos φ range from 0.7 inductive...to...0.7 capacitive.
  • Web-based performance monitoring.
  • Internal short-circuit protection.


If higher reactive power compensation capacity is required, up to 100 devices can be connected in parallel.
