Webb10 apr. 2008 · LtDoc. There are two value ratings for capacitors that are important to remember for R/C'ing. The capacitance value (something between 0.001 and 0.04), and it's voltage rating (something at -LEAST- twice the applied voltage, bigger is better). After that, it's a matter of what you find thats fairly common. Webb13 juni 2024 · Required Capacitor kVAR = P (Tan θ1 – Tan θ2) = 5kW (0.74 – 0.14) = 30 kVAR. And Rating of Capacitors connected in each Phase. 30/3 = 10 kVAR. so ideally capacitor of 30 kvar is required but many a time it is suggested to use a little 5% lesser than 30 kvar due to over-voltage issue. so in this case, 28.5 kvar is perfect to use.
