Chint BZMJ Low Voltage Self-healing Shunt Capacitor Banks for Reactive Energy Compensation and Power Factor Correction
General
Power factor determines how well you use your power. It’s the simple ratio of your real power over your apparent power. The general engineering practice or rule of thumb is to keep your power factor number as close to 1 as possible. Why correct power factor? Correcting power factor can reduce your utility bills, reduces apparent power and loading on your distribution network, reduces carbon emissions, and improves voltage regulation. The most cost-effective way to correct power factor is to use automatic capacitor systems suitable for small, medium, and large network installations.
