6 FAQs about [Use static capacitor to adjust voltage]
Why is a static capacitor used in a power system?
Static Capacitor We know that most industries and power system loads are inductive, which causes a decrease in the system power factor due to lagging current (see disadvantages of low power factor). To improve the power factor, static capacitors are connected in parallel with these devices operated on low power factor.
