Good morning all,

I'm looking for recommendations on a training course in three phase supply, types of transformers and their safety and testing. I've got a good basic knowledge of the types of transformers but I am conscious that a gap in my knowledge is the differences between them and the safety implications of using the different types. Apologies this is a bit vague but I'm not really sure what else to ask! Any recommendations would be extremely helpful.

Thanks in advance!

Tom
