Steam turbines have vibration protection systems that can also be used for monitoring and diagnostics.

The following is a schematic of the typical instrumentation applied in a steam turbine monitoring system:

The recommended parameters for monitoring this type of turbines are as follows:

  • Relative radial vibration of the shaft with respect to the bearing.
  • Absolute shaft vibration.
  • Thrust/Expansion/Position.
  • Eccentricity.
  • Speed/Acceleration/Overspeed.
  • Temperature.
  • Phase.
