compensare putere reactiva medie tensiune

 

 

Industrial consumers, in general, pay monthly for a quantity of reactive energy representing the difference between the measured reactive energy and the calculated reactive energy, corresponding to the neutral power factor (0,92).

In order to eliminate these expenses, the improvement of the power factor is done through the injection of capacitive reactive energy in the consumer's distribution network.  
 

Control systems are used with ecological capacitor banks of fixed value or sequential, installed at the level of 6, 10 or 20 kV, indoor or outdoor.   

Each power factor correction switchgear is equipped with exhaust hatches in case of internal incidents (arc fault, capacitors' defects).

The capacitor banks in each switchgear are powered through a three-pole disconnector, with fuses and CLP, when you require a manual actuation, or through a fuse contactor when you require an automated (sequenced) actuation, each sequence having CLP.
