Transformer Harmonic Loss Calculation and Economic Evaluation
Yu Yan · Electrical Automation · 2013
With a large number of advanced and automated production lines based on microelectronic control technology used in modern industry,production efficiency is continuously improved. At the same time,enterprises pay more attention to power quality than ever.In order to grasp enterprise's losses caused by harmonics,portable power quality analyzer FLUKE435 is used to carry out 24 hours uninterrupted monitoring at each point. On the basis of the measured data,direct and indirect economical losses caused by harmonics are evaluated through classical theory of transformers' harmonic losses. For industrial enterprises,this method has some guidance and reference value in evaluating and calculating economic losses caused by harmonics.
