Note:

1. Original kVA: Calculated based on the current power factor.

               Original kVA=Real Power (kW)/Current PF​

2. Desired kVA: Calculated based on the target power factor.

               Desired kVA=Real Power (kW)/Target PF​

3. Required kVAR: The required reactive power to correct the power factor, calculated as:

                Qc=P(tan⁡(cos⁡−1(Current PF))−tan⁡(cos⁡−1(Target PF)))

How It Works:

1. The user enters the real power (kW), current power factor, and target power factor.
2. The calculator computes the original apparent power (kVA) and the desired apparent power after correction.
3. It then calculates the required kVAR to bring the power factor to the desired level.
4. All results (original kVA, desired kVA, and required kVAR) are displayed on the screen.

Example:

• If the real power is 100 kW, current PF is 0.7, and target PF is 0.95:
  • Original kVA will be approximately 142.86 kVA.
  • Desired kVA will be approximately 105.26 kVA.
  • The required kVAR to correct the power factor will be calculated and displayed.

This enhanced version is useful for understanding the impact of power factor correction and helps in determining how much capacitance is needed to reduce apparent power, resulting in more efficient energy use.
