- New Yorker Electronics has released an enhanced Cornell Dubilier(CD) PC series of AC harmonic filter capacitors
- Cornell Dubilier has extended the capabilities of the series by upgrading the RMS rating of the capacitors up to 85 A
The Effects of Harmonics on Capacitors include additional heating – and in severe cases overloading, increased dielectric or voltage stress, and unwanted losses. Also, the combination of harmonics and capacitors in a system could lead to a more severe power quality condition called harmonic resonance, which has the potential for extensive damage. Consequently, these negative effects will shorten capacitor life.
PC capacitors are designed to meet the demands of filter applications rich in system total harmonic distortion (THD). This series has a dual protection system. It utilizes a self-healing metallized polypropylene. It also has a mechanical pressure interrupter. This ensures a safe open circuit mode in the event of overload or end of life.
Runs an internal pressure interrupter system
New Yorker Electronics has released an enhanced Cornell Dubilier(CD) PC series of AC harmonic filter capacitors. According to the company, the capacitors have been upgraded with series improvements. It includes the UL-recognized construction and internal pressure interrupter system. This internal system passes rigorous UL testing. This testing ensures fail-open performance under high current fault conditions. The higher current ratings improve the capacitor’s ability to handle the high levels of harmonic content. These harmonics are encountered in inverter AC input and output filtering applications.
Can connect in delta or wye configurations
Minimises hating of capacitors
Capacitor customisations available
Also available in rack-mount systems
The PC series enhancements add capabilities to the broad range of AC harmonic filtering solutions offered by New Yorker Electronics. These series include three-phase cylindrical and welded rectangular cases. These cases are used in large inverter systems. In addition to this, Cornell Dubilier(CD) manufactures also manufactures rack-mount systems. These systems are in-house fabrications by CD. It allows easy integration of capacitor banks into the mechanical design of a filter system.
