Three Phase Power Calculator

Using the Electrical Calculator Application

The Electrical Calculator application is designed to simplify the process of calculating electrical parameters for both single-phase and three-phase systems. This guide will walk you through how to use the application and explain the relevant formulas for each type of calculation.

Getting Started

1. Select the Calculation Type:

   The first step is to choose the type of calculation you need. You can select between:

   • Single Phase
   • Three Phase Star
   • Three Phase Delta

Single Phase Calculation

Input Parameters:

• Voltage (V): Enter the voltage value. You can select the unit from Volts (V), Kilovolts (kV), or Megavolts (MV).
• Current (I): Enter the current value in Amperes (A).
• Power Factor (PF): Enter the power factor, a value between 0 and 1.

Formulas Used:

• Apparent Power (S): S = V × I
• Active Power (P): P = S × PF
• Reactive Power (Q): Q = √(S2 - P2)
• Power Factor Angle (θ): θ = cos-1(PF)

Three Phase Star Calculation

Input Parameters:

• Voltage (V): Enter the voltage value. You can select between Line Voltage and Phase Voltage. Choose the unit from Volts (V), Kilovolts (kV), or Megavolts (MV).
• Current (I): Enter the current value in Amperes (A).
• Power Factor (PF): Enter the power factor, a value between 0 and 1.

Formulas Used:

• Line Voltage (V_L) and Phase Voltage (V_Ph): VL = √3 × VPh
• Apparent Power (S): S = √3 × VL × I
• Active Power (P): P = S × PF
• Reactive Power (Q): Q = √(S2 - P2)
• Power Factor Angle (θ): θ = cos-1(PF)

Three Phase Delta Calculation

Input Parameters:

• Voltage (V): Enter the voltage value. Choose the unit from Volts (V), Kilovolts (kV), or Megavolts (MV).
• Current (I): Enter the current value in Amperes (A). You can select between Line Current and Phase Current.
• Power Factor (PF): Enter the power factor, a value between 0 and 1.

Formulas Used:

• Line Current (I_L) and Phase Current (I_Ph): IL = √3 × IPh
• Apparent Power (S): S = √3 × V × IL
• Active Power (P): P = S × PF
• Reactive Power (Q): Q = √(S2 - P2)
• Power Factor Angle (θ): θ = cos-1(PF)

Viewing Results

After entering the required inputs, the application will automatically calculate and display the following results:

• Apparent Power (S): Displayed in VA, kVA, MVA, or GVA depending on the magnitude.
• Active Power (P): Displayed in W, kW, MW, or GW depending on the magnitude.
• Reactive Power (Q): Displayed in VAR, kVAR, MVAR, or GVAR depending on the magnitude.
• Power Factor Angle (θ): Displayed in degrees (°).

Conclusion

The Electrical Power Calculator accurately calculates electrical parameters for both single-phase and three-phase systems. By following the steps outlined above, users can quickly obtain the necessary values for their electrical calculations, making the process efficient and straightforward.
