Calculator
Reactive power calculator
Calculate capacitor bank power, reduce line current and calculate monthly savings with reactive power compensation.
Calculator results are indicative only. Final parameter selection and installation execution require verification by a qualified engineer. Each case may require additional factors and individual calculations accounting for site-specific conditions and technical requirements.
