Harmonic Distortion Calculation Load Side of Isolation TX

07/18/2012 8:17 PM

Hi everyone!

I am considering the use of a isolation TX to protect a UPS from a service with high harmonic distortion system. If you know the harmonic distortion of the service (and the % of the harmonics) how do you calculate the power harmonic distortion on the load side of the isolation transformer?

The TX will be 4 kW single phase.

Thanks!

Thanks for the reference. I am reading now.


Usually the isolation transformer is described as a device that keeps harmonic distortion on the load side of the TX and prevents the line side from getting that harmonic distortion.

I wonder if it could work the other way around?

Can an isolation TX can be used to reduce the harmonic distortion on the load side of it when the line side contains high levels? In other words, can the isolation transformer show less harmonic distortion on the load side than in the line side?

Any comments or experience is welcome!
