Morning dry air skid checks, water pump, kobelco, drying towers all nominal.
Dew point measurement at HAM1 , approx. -42C
The turbo on the YBM tripped as a result of the power glitch reported last night see alog 84217, leading to a slight pressure rise in the corner.
I closed the main gate valve at that turbo and restarted the scroll pump/backing turbo and main turbo. Once the turbo reached full speed and the intake pressure was lower than the main volume pressure I verified trip setpoints and re-opened the gate valve..
This was the only turbo station that tripped. Output tube/XBM & HAM6 turbos were all nominal.
