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.
Known variables: Capacitor Frequency, Capacitor Voltage and Capacitance
Known variables: Capacitor Frequency, Capacitor Voltage, and Reactance
For application of the above rated capacitors on systems that deviates from their nameplate value, use the calculators below. Calculator-3 uses calculator-1 input values. Calculator-4 uses calculator-2 input values.
Known variables: Capacitor Voltage and Capacitor Frequency
