Hi,
On the plant at which I work we have the convention that on voltage transformers the white phase is tied to earth and the neutral left floating. I believe this arose from the installation in the 50's (Reyrolle gear) and has continued since.
My question is does anyone know of the reason...
I am looking into a review of motor re-acceleration times where I work. What I need is a reference on how to determine the speed of a motor driving a load (compressor, pump ...) at any time after a complete power loss. If anyone has any good links or references they would be appreciated...
