575V vs 460V Coordinated Drives for Papermachines
575V vs 460V Coordinated Drives for Papermachines
(OP)
I have been on several Pulp and Paper Projects in the recent past where the project direction took the coordinated drives on a 575V power system and the 480V loads consisted of FVR/FVNR/non coordinated VFDs, etc.
Is this a client preference or is there a motive to doing this? I have tried to research this and have not been successful in determining this. Thank you in advance for your comments.

I see petro-chemical plants with a plant utilization of 600 Volts (575 Volts).
But 480 Volts is a common heat trace controller voltage.
So, motors and lighting transformers are 600 Volt based and the heat tracing is 480 Volt based.
Note: I am in Canada where 600 Volts is a standard utilization voltage. This scheme may be more common in Canada.
