IEEE C57.21-1990 - IEEE Standard Requirements, Terminology, and Test Code for Shunt Reactors Rated Over 500 kVA

Standard

Superseded

Standard Details

All oil-immersed or dry-type, single phase or three-phase, outdoor or indoor shunt reactors rated over 500 kVA are covered. Terminology and general requirements are stated, and the basis for rating shunt reactors is set forth. Routine, design, and other tests are described, and methods for performing them are given. Losses and impedance, temperature rise, dielectric tests, and insulation levels are covered. Construction requirements for oil-immersed reactors and construction and installation requirements for dry-type reactors are presented.
