This is a capacitor bank control panel that we installed in 2019, as energy efficiency is becoming increasingly in demand in recent times. Capacitor bank is a good way to maximize the power efficiency. For this project, we installed the capacitor bank to a 800A and 1000A main switch board respectively.
For the 800A MSB, a 4 step capacitor bank (200kVar) is used to manage the reactive power. While for the 1000A MSB, a 6 step capacitor bank (300kVar) is used to manage the reactive power.
After our installation, we managed to correct the power factor from 0.6 to 0.9. This can be shown below by the current the ammeter reads on the main switch board where it decreased drastically. Hence, with the power factor increased, the apparent power is reduced and the real power is increased. In a long run, the cost savings will be enormous due to the reduced apparent power and the factory will be more energy efficient.

Resultant Power Factor
This is a power factor correction controller that we use to regulate and automatically cut in the capacitor steps. As seen, after cutting in 6 steps, the power factor rating of the system increased to 0.93, running at 848A.
