Method We Use When Turbine Trips and Do Not Know What Is the Logic Cause

I want to share a method that we use when we have a trip of unit and do not know what is the cause and which may be due to several signals. For if it could be useful to someone.

Using the Toolbox and contact block software alarm caused by the trip, the unit restarts and the program video recording of the computer screen where it is installed the Toolbox, is activated. When the trip occurs (primarily occurring trips the starting unit), it proceeds to viewing the video to make sure that contact is activating the trigger block.

This method we have used in trip caused by the SRV during the start of unit, when performing the Test B, making two videos found that the activated block that was the time allowed to open the valve, we changed the MOOG and the problem was solved.
