Abstract
The correction of the transformer time constant as affected by initial temperature rise and loading is accomplished by nomograms for representative cases of transformer temperature rise as a function of watt loss. Possible errors in computing insulation aging are indicated in an example using the corrected versus the uncorrected time constant. A method is given for making many determinations of a transformer time constant from a single set of data without use of ultimate temperature rise.Keywords
