DETUNED FILTER CAPACITOR BANKS
All electrical devices require active power in order to function. Many electrical devices, such as electric motors, also require reactive power. The reactive power can be taken from the power grid, in which case the electricity company charges a reactive power fee. The other option is to generate reactive power locally with a detuned filter capacitor bank.

REACTIVE POWER REQUIREMENTS
Harmonic flows occur in power networks due to non-linear loads, such as computers, frequency converters and UPS equipment. Among other things, the harmonic flows increase losses and cause malfunctions in electrical devices. A detuned filter capacitor bank filters out common harmonic flows.
In selecting the detuned filter capacitor bank, the system’s reactive power need and fluctuations in the need must be known. The reactive power need is usually evident in the electricity bill. In more complex systems, reactive power need and harmonics are verified by measurements.
SELECTING THE DETUNED FILTER CAPACITOR BANK
A detuned filter capacitor bank is comprised of suitable compensation steps. The steps are selected depending on the fluctuation of compensation needs in the system. Typically, a suitable combination of small (e.g. 12.5 kvar), medium (e.g. 25 kvar) and large (e.g. 50 kvar) compensation steps are needed. The controller turns the compensation steps on/off as needed. If the traditional floor model detuned filter capacitor bank is too large or cannot be installed on the floor for other reasons, we recommend our wall-mounted capacitor banks.
The detuned filter capacitor bank is tuned to a frequency not found in the grid (in Northern Europe, this is usually 189 Hz). Other tuning frequencies can also be used.
