KRL-FO type detuned capacitor bank for grids high in harmonics with 7% (189Hz) or 14% (134Hz) reactors

FO-type detuned power factor correction unit with 7% (189 Hz) or 14% (134 Hz) detuning factor for highly polluted networks

Detuned reactive power compensation device with harmonic filtering reactors in a standing cabinet. To reduce power factor, improve system efficiency and reduce energy losses for fast ROI.If required, we also manufacture equipment with different step allocations and outdoor designs. The equipment has a modular structure and can be easily expanded. In case of higher performance requirements, the system can be expanded with additional FOP type devices. In case of special reqirements special design is possible. In order to optimize the number of steps (steps), 75 kvar step is also available.
