Howdy All, I'm trying to get an idea of what sort of voltage fluctuations(AKA Flicker) would be possible back through a step-down transformer onto the HV power grid based on known voltage fluctuations generated the secondary. I'm not sure what the HV feed is (7200, 4000, or 480VAC). The "EUT" in this case has the potential to generate between 3%-15% (at 120Vac) voltage drops based on the AC mains impedance. I would like to calculate how the primary of the HV step down transformer is changing based on instantaneous changes on the secondary.
Is it as simple as n= Vs/Vp = Ip/Is ? Thanks for any pointers on this Regards Dave Spencer Xerox Corp - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
