Thyristor Switching Modules (TSM)
Brawn Energy offers Thyristor Switching Module, specially designed for Real time Power Factor Correction (RTPFC) applications. RTPFC is designed to compensate the reactive power on real time basis for extremely rapid acquisition of the power factor within the range of 100 – 120 millisecond. In conventional APFC method, the number of capacitor banks are selected by switching the contactors connected in series with each capacitor bank – Contactor based switching gives delayed correction and hence difficult to maintain PF close to unity. Thyristor Switching Modules are free of Mechanical Wear and Tear, operate without noise and provide practically transient free switching eliminating inrush currents which are associated with Electromechanical Contactor Switching. An unlimited number of switching operations, without applying significant stress to the capacitors. This BE-TSM module allows the selection of such capacitor banks using thyristors which offers many advantages compared to electromechanical contactors. Brawn energy make TSM modules are available to switch 3 phase capacitor banks rated for 5, 10, 15, 25, 50, 75, 100 & 150 KVAR. Voltage level up to 900VAC. Zero cross over switching technique is used to rapidly turn on and turn off the thyristors connected in series with these capacitor banks. These switching modules (TSM) are easy to install and come with built-in indications for normal function and faults, along with built-in protection circuits for fail-safe operations.
