Floating-Y Connected versus Grounded-Y Connected Transformer 2

[PE56]

What are the benefits of connecting a transformer with a floating-Y or a grounded-Y? What applications are most common for each connection? What are the advantages or disadvantages of each type of connection? What is likely to happen if you don't have that return path to a grounded Y-connected source?

There's a really good paper published by GE many years ago called The whys of the wyes. Well worth a read, and will probably answer all your questions plus a few you haven't thought of yet.

Interesting read. I especially liked the cost, "Suggested Price 50 cents".
