Harmonic Frequency Calculator

Use the calculator below to find the harmonic frequency as well as find their phase rotation sequence as used in power system engineering. Refer to sequence components to find more details on  and harmonic phase rotation.

Capacitor Bank Resonant Frequency Calculator

Use the calculator below to find the parallel resonant frequency when applying capacitor bank in a power system. Capacitor bank calculation for transformer needs to be performed to identify and avoid potential resonance condition between capacitor bank and source inductance. When calculating kvar for transformer, considering the potential for resonance is a good engineering practice. Refer to source impedance calculation in power system to gather additional information on calculating short circuit MVA.
