The National Electrical Manufacturers Association (NEMA) recently released CP 1-2000, its new standard for shunt capacitors.

The standard provides manufacturing, rating, and testing standards under various service conditions, and application and operation guidelines for capacitors for shunt connections to AC power transmission and distribution systems at 50 Hz or 60 Hz and below.

Shunt capacitors are used in air conditioning, electronic power conversion, fluorescent and high-intensity discharge lighting, and other industrial and utility applications.
