The use of power quality standards to establish an equivalent transformer capability under harmonic loading

Transformers which are not designed to operate under harmonic loading will experience higher than usual temperature increases in the windings due to the added harmonic current. This paper uses the IEEE 519 and NRS 048-2 power quality standards which define harmonic limits of voltage THD (Total Harmonic Distortion) and IHD (Individual Harmonic Distortion… CONTINUE READING
