Nice concise video. So what is the difference in a step up vs a step down when above 75kVA? I sell generators as large as 3000kW and often people want MV output. The generator will only produce 10x current, and the instantaneous can be set above that, but what specifically would I want to know about the anatomy of the transformer to make sure it is appropriate?
Hi Curt, The best way to find the type of transformer that would meet your specific need would be to reach out to one of our technical sales reps. Please send us a message: www.maddoxtransformer.com/contact
Correct me if I’m wrong but your graphic showed a single phase 208v being converted to 480v three phase. Based on my knowledge, H2 and H3 will have 0v.
Great question. In the graphics for this video we are showing a transformer being reverse fed to step up 208v 3-phase to 480v 3-phase. In this scenario, the neutral X0 terminal on the 208 side is not used. Also, the 480 side does not provide a neutral since the winding is delta connected.
