Power Factor Correction Capacitors
- Thread starter afterhrs
- Start date
Capacitors are a self-contained shunt load. They draw a fixed current that is a function of the capacitive reactance and the voltage. Doesn't matter if there is any other load or not.
That's why capacitors are often switched directly with the motor rather than bus connected.

PF capacitors produce reactive power {VARs or reactive voltamperes} in AC-power systems. Induction motors consume reactive power {VARs} and real power {Watts}. Both cause current flow through AC conductors.
