Detuned Capacitor Bank

The Detuned Capacitor banks offered by Saumita Controls include both Contactor switched or Thyristor switched depending on nature of loads connected in the Electrical Network. Thyristor switched capacitor panels have many advantages such as the following: Very fast / real time response to changing loads. Response time less than 1 sec. Due to very fast capacitor bank operation maintaining PF near unity is possible, especially where billing is based on KVAh instead of Kwh. Soft / solid state switching of the capacitors by the thyristor modules eliminate the high inrush currents and voltage sags produced in std. APFC panels. Elimination of high inrush currents and voltage sags is beneficial for the connected electrical equipment. Due to this soft switching the life of power capacitors is 3 to 4 times more than in std. APFC panels. The Detuned capacitor Banks offered by Saumita Controls are designed and manufactured based on following design criteria and Specifications:- Capacitor bank with 7 % or 14 % Detuned reactors with suitable rated capacitor (Voltage& KVAR) & Detuned Reactor (mH & Current) to suit harmonic levels in the network. Harmonic Levels are determined based on Harmonic simulation Studies (Design Stage) or in the event of retrofits after Site surveys. Eliminates harmonic amplification. Enhances the life of capacitors by reducing voltage and thermal stress due to harmonics Improves Power Factor in harmonic rich environment.
