Nagwa,

I noticed after I sent the sample to you that it did not include Gen Temps.
The data sets that I provide next will include those values. The turbines I
selected to use were:7, 28, 50, 65, & 78. If you have other suggestions
please make them. Due to other obligations, I will not be able to get you the
data until tomorrow morning.

Nagwa,

I'm attaching a sample of the output of your request (one turbine, #001).
Please make sure all the fields you need are here.

The logic I used is as follows

(1) Find the moving average of Power (KW) using a 50 minute (5 record)
interval.
(2) For all 10-minute records where the moving average is <= 1490 find the
maximum amb. temp.
(3) Find a record where both conditions are true, high temp/high power. I
added a marker (=1) for the selected record
(4) Make table +/- 12 hours from the marked record (should have close to 144
records).

If either the logic or the fields selected need adjustment let me know.
