TURBINE SUPERVISORY INSTRUMENTATION

INTRODUCTION TO TURBINE SUPERVISORY INSTRUMENTATION 
 [ TSI ]

WHAT IS TSI?
System which supervises turbine with the help of instruments.
   
AIM :-
Monitors some important parameters which directly or indirectly are linked
& predict the healthiness of turbine.

TURBOVISORY PARAMETERS

VIBRATIONS:-
     1.SHAFT VIBRATION
     2.BEARING VIBRATION

TURBINE EXPANSION:-
     1.ABSOLUTE EXPANSION [ HIP/LP ]
     2.DIFFERENTIAL EXPANSION[HIP/LP ]
     3.AXIAL SHIFT

SPEED MEASUREMENT:-
     1.KEY PHASOR 

ECCENTRICITY
