Turbine Supervisory Instrumentation (TSI) is a generic term used in the power generation industry. TSI refers to instrumentation systems that specifically perform measurements of critical control parameters on large steam turbine generator trains. TSI systems are normally a mandatory requirement. The same technology is employed on other turbine types and in other industries, such as the hydrocarbon-processing sector.
Emerson has different TSI solution for different industries. However in these areas, different terminology tends to be used. A detailed examination of each specific TSI measurement can be found in related Emerson Reliability Systems application notes.
