Automatic hybrid batteries

Compensation of inductive and capacitive reactive power in LV networks

Automatic hybrid batteries are designed for compensation of inductive and capacitive reactive power within low voltage networks, and constitute a combination of condenser batteries and compensation choke batteries.

They are applied at facilities where the character of loading changes due to different types of receivers. This may take place, among others, at offices where operation of the ventilation and air conditioning unit on hot days results in exceeding the tgφ coefficient, whereas during colder months where no inductive loads appear, capacitive reactive power is consumed.

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.

Automatic hybrid batteries BHL

compensation of inductive and capacitive reactive power in LV networks
facilities of variable nature, including offices, where, in hot weather, the operation of the air-conditioning unit causes tgφ coefficient to be exceeded, and in colder months, if there are no inductive loads, the consumption of capacitive reactive energy.

minimised active power losses
the controller switches on the steps necessary to ensure the given cosφ coefficient
reduced active energy consumption, by reducing active power losses
minimised charges for inductive and capacitive reactive energy
