Phase Shifting Transformers to Cancel Harmonics

When there are several non-linear loads of equal ratings in a power systems, the use of phase shifting transformers could help cancel harmonics. After harmonic filters, phase shifting transformers are one of the simplest solution…

Harmonics and Neutral Currents

Before the advent of computers, variable speed drives, soft starters and other non-linear loads, the only source of harmonics in power systems are industrial plants using arc-furnaces. These arc-furnaces require so much power that main…
