Capacitor Bank calculator or kVAR Calculation Formula
Let we calculate the required reactive power in kVAR or capacitor bank to be connected across the motor? Here, PF 1 = 0.7. PF 2 = 0.96. Required capacitor bank = 100 x tan (cos-1 (0.7)- cos-1 (0.96)) = 72.85 kVAR. Hence you can connect three 25kVAR capacitor bank across the panel for improving the power factor from 0.7 to 0.96
Per Unit Calculation | Per Unit System Examples
Per Unit = (Present value) ÷ (base value) Per Unit values are sometimes expressed as a percentage rather than a ratio. For example, if the base value of voltage had been selected as 13,800 V and the present value is 11,000 V, the value of voltage per unit is. V PU = 11,000 ÷ 13,800 = 0.797 PU, or. V PU = 0.797 (100) = 79.7% PU
