The following is a synopsis of information … The following is a synopsis of information that was provided by AMETEK Solidstate Controls Inc. via email:</br>This component (07-020139-10) is a 13 micro-Farad AC oil filled capacitor. During operation in an inverter, oil may be visible on, around, or dripping from the capacitor or its mounting bracket or tray. If allowed sufficient time, enough oil will leak from the capacitor that it will short internally and fail. Time required for the failure could be greater than the recommended 10-year preventative maintenance cycle for this part.</br>AMETEK Solidstate Controls has not been able to determine a definitive cause of the failure, but is working to do so. </br>These capacitors are generally part of a larger capacitor bank. The failure would result in a reduction of output voltage that is directly proportional to the number of capacitors in the bank that fail. Any single capacitor failure would be less than a 3 volt decrease in output voltage.</br>Users of these capacitors should visually inspect any equipment containing the capacitor part number stated above for evidence of an oil leak. A review of the output voltage for the parent equipment for any consistent decrease in voltage of 0-3V may serve as an indication of capacitor failure.
