As a general rule the correct size of capacitor for individual correction of a motor should have a kvar rating not exceeding 85% of the normal No Load magnetizing KVA of the machine. If several motors connected to a single bus and require power factor correction, install the capacitor (s) at the bus.
Wiring a capacitor might seem daunting, but with the right knowledge and guidance, it becomes a manageable task. Whether you’re a DIY enthusiast or a professional, understanding the intricacies of capacitor wiring is crucial for various electrical projects.
No, as long as the capacitance and voltage ratings are the same, the physical size of an electrolytic capacitor is unimportant. A possible exception is if the switching power supply uses low ESR capacitors, in which case the sizes may change. The performance of all capacitors is not the same. Using a larger cap is not always the best solution.
When sizing a capacitor, always choose one with a voltage rating higher than the maximum voltage in your circuit to prevent breakdown and damage. The capacitance value, measured in farads (F), indicates the amount of charge a capacitor can store for a given voltage.
In most circumstances, the physical size of the capacitor is directly proportional to the voltage rating. A motor will not run properly if the capacitor is not of the appropriate size. This is not to say that greater is better, because an overly large capacitor might increase energy usage.
The most accurate method of selecting a capacitor is to take the no load current of the motor, and multiply by 0.90 (90%). Example: Size a capacitor for a 100HP, 460V 3-phase motor which has a full load current of 124 amps and a no-load current of 37 amps. Size of Capacitor = No load amps (37 Amp) X 90% = 33 Kvar Go to Content ↑ 2.
