Improve the power factor to bring the advantages of technical and economic:
- Allows the use of transformers, switchgear and cables smaller.
- Reduced penalties for reactive power consumption kVAr
- Reduced power losses, voltage drop in the electrical network.
With the cabinet equipped with capacitor capacitor is then automatically controlled devices for controlling power compensation automatically, keep the power factor in a permissible limits around the value factor Productivity is selected.
The device is installed at the locations of active and reactive power changes in a very wide range. For example, at the busbars of the main distribution panel, in the connector of the cable under axial load.
In general compensation rules:
- If the capacity of the capacitor (KVAR) less than or equal to 15% of the rated power supply transformer, use ground-based compensation.
- If above 15%, you should use automatic compensation manner.
- Location installing capacitors in the power network taking mode power compensation, or compensation to focus, make groups, or a combination of local compensation plan last two.
In selecting the optimal capacitor size can be selected by simple methods based on conditions or pay a fine.
