Capacitor: Results
built 647 days ago
The results showed 18 of the 20 standard capacitor test pieces failure due to broken leads, with a failure rate of 90%. In contrast, none of the 20 vibration-resistant capacitors had broken leads, with the failure rate of 0%. The vibration-resistant types showed a huge improvement in vibration performance.

For single-phase applications, the three-wire yoke allows the capacitor to be moved out of the packer and into a redesigned control box. Troubleshooting is easier, as checking or replacing the capacitor no longer requires removing the manhole cover and climbing into the sump. Result: easier maintenance and less site shutdown.

The duration of the ring-wave transient is dependent upon the system X/R ratio at the capacitor bank. Systems with higher X/R ratios result in longer duration transients. Transients associated with substation capacitor banks can last as long as long at 30 to 40 cycles.
