In this article, we will discuss testing of capacitors for electric motors in general and tests associated with specific uses of capacitors such as for power factor correction, and for electric motor starting (see Figures 1 and 2). For information on sizing power factor correction capacitors see Subsection 2.10 of the EASA Technical Manual, and for determining the correct size capacitor for a motor, see Subsection 2.11 of the EASA Technical Manual.
