Re: Total Down Time

What definition of down time do you mean? If the GEWE definition, the time
when the turbine is faulted off automatically or in a repair status, is used
then yes your are correct. If the customer definition, when the turbine
can't produce power in good winds, then you are incorrect. The turbine
can't produce power during manual pause mode or in transition between
states. During calm months, the turbine should not frequently be in
transition. Manual pause should be uncommon as per management direction.

Subject: Total Down Time

As a verification of understanding;

Total Down Time = TO - (DT + RT +LOT + MT + EST + WOT)

Where TO = Total possible survey time.

Thanks,
