    CALCULATION OF CAPACITOR KVAR

    The calculators on this web page are used to calculate kvar and other capacitor parameters for single-phase capacitors commonly used on medium voltage capacitor banks and harmonic filter banks. Use calculator-1 when capacitor voltage, capacitance, and frequency are known. Use calculator-2 when capacitor voltage, capacitive reactance, and frequency are known.

    Also on this page are calculators (calculator-3 and calculator-4) for applying capacitors on systems that deviate from their nameplate rating. Use these calculators to determine resulting output kvar and current for your specific application.
