It is used in the AC power distribution system terminal with the 1 kV voltage or more to increase power factor,to reduce ciruit loss,to improve the output of the transformer and to make the motor economically operated.It is used paralleled with the motor and the inductive load to automatically tracking compensate to the frequency factor.TBBW2 merged measurement and Compensation funceions into 1,it is the best choice for low-voltage side compensation of tranformers.
Operating standard:IEC439,GB7251-97,JB7113-93.
