Transformer mag current
(OP)
Hi
What would be the typical range of magnetizing current for power transformers in the 50KVA - 500KVA 11KV/400V be? percent of rated current.
Best regards,
Mark

RE: Transformer mag current
Had to use a German expression that I recently learned. It means: "Just this question, I cannot answer with enough certainty, so I do not answer. Not this time. I can answer any other question, of course, but not this one. At least not with the certainty you need and deserve. You really ought to know what questions to ask! This is not a good question to ask."
Apart from that, it depends a lot on how close to saturation the flux is taken. And what the core material is. One guy that I know, is making a distribution transformer with extremely low magnetizing current. The reasoning is that rural distribution transformers idle a lot and that the idling losses shall be minimized. I will be back with his home page when I have found it.

If you browse the site (http://www.hexaformer.com), you will find data on idling and full load losses for different transformer sizes. But nothing on magnetizing current.
I think that prc's data for wound core transformers are close to what you find in these transformers.
