Episode: Short 15 - Testing Capacitors, A Practical Approach
Description: In this short podcast episode, Bryan Orr discusses the best practice methods for testing run capacitors in the field. We understand the capacitor to be a voltage storage device. We can benefit from comparing the capacitor to a balloon that inflates and deflates with electrons as the alternating current changes (60 times per second). A capacitor causes a phase shift and allows there to be current on the start winding. So, when a run capacitor fails, you won't have current on the start winding. The old-fashioned way of testing a run capacitor was to take an...
