Yes TSI stands for Turbine Supervisory Instrumentation.

But its not such a easy thing to understand. Turbine is the
Soul of any Power Plant. The job of every Engineer in any
Thermal Plant is to give maximum protection to the Turbine.
For that this TSI concept is there.

In order to protect our turbine we use more then 100 sensors
all around the turbine body depending upon the size or the
capacity of the turbine. These Sensors include
Thermocouples, RTD , Pressure gauge , pressure transmitter ,
temperature gauge, bi metal thermometer , temperature switch
,pressure switch . But most important Thing that we do for
the protection for a Turbine is we erect Vibration Sensor ,
Speed Sensor , Differential Expandtion (DE) semsor, Casing
Expandtion Detector or sensor (LVDT).

All these instrument gets the field result and send it to
the TSI. The TSI evaluate all the input from all these
sensor and control the governing valve and other related
Mechanism for a safe working of turbine.

But before we install all these instrument it is most
important that all these instrument should be thoroughly
Calibrated and their record b store prior being installed on
the field.
