Thyristor switching of capacitors for power factor improvement has many advantages over conventional contractor switching. Thyristor Switching is highly with minimum maintenance, especially suitable for fast variable loads, where contractor Switching systems fail to give desired results. The capacitors are switched at'' ZERO CURRENT CROSS OVER THRESHOLD''Automatic power factor correction is typical for large electrical systems with fluctuating load where it is common to connect number of capacitors to main power distribution station or substation. The capacitors are controlled by controller which continuously monitors the relative power demand. The relay connects or disconnects the capacitors to compensate for actual reactive power of the total load and reduce overall demand supply. Thyristors are used to switch the capacitors On and Off in the system.

ABB active filters can be applied to small, medium or large applications and are suitable for both industrial and commercial installations. They provide harmonic mitigation, load balancing and step-less reactive power control for inductive and capacitive loads. Selection from the large choice of ratings from several tens of Amps to several thousands of Amps enables the optimal solution for each system to be easily defined. The desired filter rating can be obtained by combining different master and slave units. Under normal conditions, the load of the filter will be distributed evenly over all the filter units operating in parallel.
