Capacitor banks are mainly installed to provide capacitive reactive compensation/ power factor correction.
Normally in factories or other high power consuming places, most probably there will be a consumption of the inductive load. Inductive voltage means that there must be a lagging power factor. In order to reduce the tariff & utilization of power, the power factor must be taken near to 1.
To do this we supply a capacitive load to compensate for the inductive load. This is the system of a capacitor bank.
The power factor regulator combines comprehensive operation with user-friendly control setting. It uses numerical techniques in computing the phase difference between the fundamentals of current and voltage, thus precise power factor measurement is achieved even in presence of harmonics.
The power factor regulator is designed to optimize the control of reactive power compensation. Reactive power compensation is achieved by continuously measuring the reactive power of the system. and then compensated for the switching of capacitor banks. The sensitivity setting optimizes the switching speed.
With the built-in intelligent automatic switching program, the power factor regulator further improves switching efficiency by reducing the number of switching operations needed to achieve the desired power factor.
