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 liquid-immersed reactors and construction and installation requirements for dry-type reactors are presented. This standard also covers thyristor-controlled shunt reactors used in static var compensators. 606 $aElectric reactors, Shunt 606 $aElectric transformers 615 0$aElectric reactors, Shunt. 615 0$aElectric transformers. 676 $a621.314 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910498509903321 996 $aC57.21-2021$93653465 997 $aUNINA
