BDKL- xx/xx batteries for compensation of capacitive reactive power

Automatic batteries of compensation chokes are designed for compensation of capacitive reactive power within low voltage networks.

Capacitive reactive power appears usually within facilities with an extensive cable network, in server rooms, in case of using UPS units and within facilities with a high number of LED light sources. For consumed capacitive reactive power (also referred to as returned reactive power), electricity supply network operators charge additional penalties which, in extreme cases, may be higher than the charges for consumption of active power.

The battery is usually composed of several steps made up by the protection, connector and compensation choke. Based on measurements, the LRM001 reactive power controller connects to the network only the steps necessary to ensure the predefined cosφ coefficient. This solution allows minimising active power losses – only the chokes necessary for avoiding additional reactive power charges work.
