Checking Power Capacitor Banks for Failed Capacitors
Shorted Capacitors - Typically the DMM will show over-load or -O.L- for a completely shorted capacitor. Open Capacitors - Typically the DMM will show a "di.sc" or a very low capacitance reading (capacitance reading in the 0 to 1 nF). Partially Failed Capacitors - Typically the DMM will show a capacitance reading that is more than 10% greater than …
