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.

Features:

Load P.F. correction is quick and consistently near to the set value. Total P.F. correction is achieved within few hundred milliseconds.
Fast P.F. correction reduces maximum demand more effectively, hence more savings on account of reduction in MD charges.
Single and multi stage configuration
Compensated and uncompensated filter
Switched and fixed filter bank
Capacitors are switched through thyristors at "zero current crossover threshold". Hence the capacitor connection to the mains is always smooth, transient free and absolutely without generation of harmonics and voltage spikes.

The basic purpose of Contractor Switched Automatic Harmonic Filter Panel is centralized Reactive Power Compensation with Harmonic Mitigation. Automatic control is provided using Automatic Power Factor Control relays. The switching of individual steps is through contractors or thyristors. With thyristor switching it is possible to have panels at higher voltages (upto 690 V), and with large size of single step (108-kVAR). Based on the load variation pattern, the minimum and maximum size of steps can be determined to maintain optimum power factor. These will help partly mitigate the harmonics from the system.
