System, with which different capacitance values can be connected to the mains for reactive power compensation. The capacitor battery contains 4 switching levels which can be connected and disconnected using power contactors. Each switching level can be controlled separately, internally or externally. The switching levels each consist of 3 capacitors in star connection with discharging resistors.
Capacitance values:
- Switching level 1: 3 x 2 µF, 450 V, 50 Hz
- Switching level 2: 3 x 4 µF, 450 V, 50 Hz
- Switching level 3: 3 x 8 µF, 400 V, 50 Hz
- Switching level 4: 3 x 16 µF, 400 V, 50 Hz
- Compensation power: max. 1368 VAr
