I have decided not to change my 3 phase, Wye-
Wye configured, 300KVA, 208/120 volt secondary, 12.4KV primary transformer configuration to Delta-Wye when I purchase my new trasformer for replacement of the original for one reason.
The facilities that are using this transformer and will be using the new transformer when the present transformer is replaced have MDPs which are delivering 208/120volts to the respective equipment. My MDPs will need to be configured for 240/120 volts and the equipment in the facility will see this voltage if I put in a Delta-Wye configuration. It may be that the facility was designed for a Wye-Wye in the first place because the equipment inside the facility requires 208/120 volts for 3 phase and would be harmed if it saw 240/120 volts from a delta-wye configuration.
Is my reasoning sound?
