| Abstract: | The dielectric conditions which are unique to converter transformers and smoothing reactors are examined. Both steady state and transient situations are discussed. Two additional tests are recommended for this equipment - a long term dc applied potential test and a polarity reversal test. Formulae are developed to calculate proposed test levels, and guidelines are presented concerning allowable partial discharge levels during the tests. |
