Yep, I thought I would call it what it is instead of what it's called. People tend to refer to our control power as 125 VDC. It's really a string of 60 lead/calcium cells being floated at 2.23 VPC so we set the chargers to 133.8 VDC. It's higher than that during a 72 hour EQ cycle. I would not use that number during any future attempt at an arc flash study because the charger would immediately switch to its current limit servo loop during a fault.
