We have noticed that our gas turbine sometimes drops out of base load. Most of the time we see this there is a disturbance on line and TTRXS drops below TTRXP and the unit backs down for a few seconds.
We set up a VIEW2T trend to look at some parameters to verify this with L60TTRX to be the trigger. Here is what we are seeing:

It almost looks like communications were lost momentarily. Has anyone else seen this or have any thoughts to the cause?
Thanks,
