Topics I've Started

Even Harmonics

06 September 2010 - 06:16 AM

Trying to refresh my memory. We know that odd order harmonics in 3rd and 5th are filtered as part of the function of the induction motor but when pulling apart an older soft starter here I noticed they use an SCR/Diode pack. Would that not cause problems with even order harmonics as opposed to if it were and SCR/SCR. Also, do any companies actually still use that setup? Thanks

Hypermizer And Other Similar Query

04 June 2010 - 12:27 AM

I am seeing a lot of marketing recently for electrical suppl volatility stabilisation. Latest is a prduct called Hypermizer through Satel. Anyone know anything about this? Is it just more marketing? I am always suspicious when a company claims to reduce consumption by 30% and does not give details. Would this simply be a case of true power and applied power being incorrectly measured with no power factor correction factored in?
