Abstract :
This paper introduces a conservative method of estimating the composite harmonic current generated by the operation of multiple linear and non-linear loads connected to a single power distribution transformer. The author draws upon the information available from industry and proposes an intuitive expansion of the currently available “K-Factor” calculation. The proposed expansion provides a useful tool in specifying power distribution transformers for operation in a non-sinusoidal load environment
