TBBZ High voltage reactive power automatic compensator

Product overview

TBBZ high-voltage reactive power automatic compensation device: it is suitable for the powerless automatic tracking compensation of 35kV 10KV (6kV) busbar in 220kV 110KV / 35KV substation. It is mainly used in the three-phase AC power system of 3-35KV. The load fluctuation is large, but the centralized compensation still can not meet the requirements of the system. Often overcompensation or undercompensation is caused. The device can detect the reactive power needed by the system in real time, then compare it with the set value, carry on the automatic intelligent switching operation, make the reactive power of the system achieve dynamic balance, in order to improve the power factor of the system, stabilize the system voltage, reduce the wastage, and save electricity cost.
