The Method for Calculating Transformer District Line Loss Based on Current Variance
After analyzing the traditional methods of the low-voltage line loss calculation, the method for calculating line loss index by parameters (copied electricity) in examined days is given in this article. It contains the advantages of electricity method and equivalent power method and the reduction formula for calculating current variance is given. This method is simple, applied and can meet the demand for the calculation of the line loss index in transformer district basically. An instance is given in this paper at last.
