Product Introduction

TBBZ series high voltage reactive power automatic compensation device automatically tracks and compensates reactive power through the control system capacitor bank automatically according to the power grid and load conditions of 6KV and 10KV power supply buses, and the power factor reaches more than 0.9. It can greatly optimize the power quality, save losses and reduce consumption, and improve the transmission capacity of the transmission and distribution system.

For example, TBBZ10-1500 (600+900) - AK indicates that the voltage is 10kV, the device capacity is 1500kvar, and there are two groups of automatic switching, one group is 600kvar, the other group is 900kvar, single star connection, and open triangle voltage protection.
