This month's Electrical Review (a free trade magazine in the UK) has just fallen on my desk, with this text and its associated picture taking up about a fifth of the area of the front page - I'm quoting it just for interest with regard to this thread!
"Perfect Harmony? Power conditioning equipment specialist Claude Lyons has installed a 200A harmonic rejection transformer at RAF Lakenheath to reduce the problems caused by harmonic currents. The recent installation of a frequency converter had caused harmonic distortion on the low-voltage network. Cables were overheating and equipment was failing. The HRT was specified to redirect the harmful currents. After installation, Claude Lyon monitored the unit and found a reduction in the production of harmonic currents - from 72 to 19A in the main neutral cable."
