Capacitor. The capacitor has two functions; it induces voltage into the rotor as well as regulates voltage. A bad capacity will result in a low voltage reading from the generator as the power being generated will be from the residual magnetism of the rotor (usually about 2-5V). To test a capacitor, a multi-meter that can test capacitance is ...

Configuration of Capacitor bank. A delta-connected bank of capacitors is usually applied to voltage classes of 2400 volts or less. In a three-phase system, to supply the same reactive power, the star connection requires a capacitor with a capacitance three times higher than the delta connected capacitor. In addition, the capacitor with the star …
As the load voltage begins to rise, we see an abrupt spike in the capacitor current. This is current charging the capacitor and it peaks at about 180 milliamps. The total time for the charge phase is around 4 milliseconds. Once the output voltage peaks, the capacitor starts to discharge into the load.

Also, you seem to confuse yourself with capacitor voltage rating, which in this case is 400V (the maximum voltage that can be safely applied to the capacitor) and the voltage that is actually across the charged capacitor. For the calaculations of energy stored, the voltage across the capacitor is what you need to look for.
