Large Low Voltage Capacitors

The location of PCB Transformers and PCB Large Low Voltage Capacitors must be marked in addition to marking the equipment itself, by marking the vault door, machinery room door, fence, hallway, pole, or means of access." ... 

Levels five and six are low range violations. Level five violations include violations of marking requirements so long as some of the requirements have been followed. Level six violations include occasional omission of data on records and manifests, and failure to label small capacitors, fluorescent fight ballasts, or large low voltage capacitors as no PCBs. ... 

A PCB large low-voltage capacitor contains 3 lb or more of dielectric fluid and operates below 2 kV. 

PCB Small Capacitors may be disposed of as municipal solid waste, unless the owner is a manufacturer of PCB Equipment PCB large High or Low Voltage Capacitors >500 ppm PCBs must be disposed of via incineration... 

Power-Factor Correction. The induction motors used for oil-well pumping have high starting torques with relatively low power factors. Also, the average load on these motors is fairly low. Therefore, it is advisable to consider the installation of capacitors to avoid paying the penalty imposed by most power companies for low-power factor. They will be installed at the individual motors and switched with them, if voltage drop in the distribution system is to be corrected as well as power factor. Otherwise they may be installed in large banks at the distribution center, if it is more economical to do so. 

Aluminium electrolytic capacitors are exploited in a range of applications and their relatively low cost makes them attractive for printed circuits for car radios, stereo equipment, pocket calculators, digital clocks, etc. Also, the very high value capacitors are used in large photo-flash equipment and for voltage smoothing.
