multicab-R-E

Reactive power compensation up to 500 kvar

Reactive power compensation systems

The multicab-R-E compensation system is the highlight for anyone who wants to compensate for reactive power up to 500 kvar. The automatically controlled reactive current compensation system in a floor-standing cabinet was specially developed for high outputs of 300 to 500 kvar and is available with a detuning factor of 5.5% to 14%. Thanks to the plug-in modules, the system is also very easy to install and maintain.

We would be happy to advise you personally and work with you to plan your individual compensation system according to your specific requirements.
