Why Use Isolation Transformer to Feed Motor
Why Use Isolation Transformer to Feed Motor
(OP)
I recently worked on a project where they had an Isolation transformer 4160V to 4160V. I could not figure out why they would use this set up to feed a motor. Any thoughts?

The other possibility would be to limit the ground fault current that could flow into the motor stator windings if the motor goes to ground. Even a wye-wye transformer will limit the ground fault current quite a bit.
