Abstract
In this paper the effects that voltage subharmonics have on power transformers are presented. The work tackles the basic case of a single phase transformer and the phenomenon of hysteresys loop asymmetrization and core saturation is focused on. Experimental results together with simulation results, both in time domain and frequency domain, are utilized for a first insight into the physical phenomenon and for sensitivity analyses.
