VOLTAGE CALCULATION

Voltage Calculation For Single Phase AC Circuit

In this analysis, we will use the nameplate or rated voltage of any single phase electrical equipment / appliance, along with the rated power and the cable or circuit impedance, to calculate the following:-

  • 1. Voltage Regulation .
  • 2. Circuit input voltage.
  • 3. The power loss in the circuit.

    • Enter Rated Load Voltage (Vo): Volts

    Enter Load Power:Watts

    Enter Power Factor: Select for Leading Power Factor

    Enter Cable Impedance Per Unit Length:

    Resistance (Ohms) Reactance (Ohms)

    Enter Length:
