| Title | Part 21 - Improper Selection of Inverter Capacitors |
| Event Description | PRODUCT: 10 KVA inverter Model 86VC0100-15, 3 phase 480 VAC output. Limited to systems supplied to Exelon Byron and Braidwood units. Capacitors C10 through C15 part number 03-040060-00.
COMPONENT DESCRIPTION: Suppression capacitors, Ametek part number 03-040060-00, used in positions C10 through C15 on Model 86-VC0100-15 only. PROBLEM YOU COULD SEE: Capacitor could arc internally and open internally and externally. CAUSE: the manufacturer's investigation revealed that due to improper selection of capacitor used may fail due to a corona effect internally. EFFECT ON SYSTEM PERFORMANCE: The capacitor may short internally and open circuit by forcing lead separation from the device. ACTION REQUIRED: Replace the capacitor(s) with Ametek part 03-040041-20. The replacement is rated at 370 VAC and used in a 277 VAC circuit. AMETEK SOLIDSTATE CONTROLS CORRECTIVE ACTION: The defect is limited to the units supplied to Exelon Byron and Braidwood plants under Ametek joc C103552. Both the Byron and Braidwood plants are already informed of this condition. |
