I realize that this a code forum, but I also realize that there is a lot of electrical knowledge resource on this forum.

We have an isolation single phase transformer (1KVA 480Pri 220Sec) that we are experiencing some issues with. With no load on the secondary we experience current reading off the primary side of this transformer. We are getting 1.5 to 2.0 amps from the primary with no load on the secondary.

This is a first for me?.

Sounds like a fault in the transformer.
Shorted turns or insulation failure maybe.
At that sort of rating, it's replace rather than repair.
