Hi All,
Here in our plant all the lighting transformers are 480V primary (Delta) and 277V secondary (Star-Y). I want to convert this transformer to give 220/230/240 secondary voltage without rewinding it. Transformer primary input tapping are 500-492-480-469-456-445-435. If I connect 480VAC to 500volt tapping what would be my secondary voltage? If the secondary voltage is within limit, is it safe to use like this. What are the effect on total KVA and is there any loss expected?
Regards,
Shree
