This standard is addressed to manufacturers, service providers and operators of steam turbine plants and is  in particular to assist operators in equipping their steam turbine plants.

The safe operation of steam turbines makes great demands on monitoring, limiting and protection devices.

In order to keep pace with the rapid development in this field, the Technical Guideline “Monitoring, Safety and Protective Equipment on Steam Turbine Plants” issued by the VDEW in 1967 was last revised in 1998 by the VGB Working Group “Turbine Operation” in the Technical Committee “Steam Turbines and Steam Turbine Operation”.

After many years of good experience with the application of this VGB Guideline, a revision of the Guideline became necessary with the transfer of the Guideline into VGB-Standard VGB-S-103, especially due to the changes in the design of monitoring, safety and protection equipment caused by digitalisation. It should be considered  on a case-by-case basis whether this guideline is to be applied in a meaningful way for older steam turbine plants. It therefore also contains information on retrofitting options.
