Dears:

can any one help me?

What is the proper time and temperature of the turbine to adjust the steam turbine differential expansion when the turbine in cold or hot status.

we have Bently Nevada probes, cable, and proximitter.

Best Regards
 
Dear,

In my experience, differential expansion sensors are typically set when the turbine is "cold", and with the rotor in what's considered to be the "normal" position (against the active face of the thrust bearing). This is so that as the turbine and shell (casing) warms and expands the differential can be compared to a known position and comparisons can be made to a known position.
