abstract:-

Investment casting is an industrial process based on lost-wax casting. Investment casting is an advanced metal forming process used to produce metal parts in high quality, functionality and cost-effectiveness. Lost wax casting process is a one-to-one process in which one disposable pattern produces one metal part. When combined with ....etc

A technique for on-line detection of incipient faults in the windings of turbine - generator rotors has been developed based on the twin signal sensing method. To detect the developing shorts in any winding, two identical pulses are applied to both ends f the winding and are reflected back .Any abnormality in the winding results in the applied signals being reflected through nonsymmetrical circuits. The difference between the reflected signals are amplified and used as signature signal for further processing. This paper describes the developmen ....etc

hello,i am final year student of electrical and electronics engineering
i want to do a mini project on technique for on-line detection of shorts in fields of turbine generator rotor.
what are the shorts and how they occur in turbine generator rotor.
and how to apply this technique , where we can apply this technique,and what are the tools used in this project.
so mail me the complete details of this topic to do as a project as soon as possible

TECHNIQUES FOR ONLINE DETECTION OF SHORTS IN TURBINE GENERATOR ROTOR

CAUSES FOR SHORTED TURNS
COIL FORESHORTENING
END-STRAP ELONGATION
FOREIGN MATERIAL CONTAMINATION
BLOCKING PROBLEMS

1.COIL FORESHORTENING
BODY CU CANT EXPAND FREELY
MINIMISE BY USING MATERIALS WITH
SUFFICIENT YIELD STRENGTHS

WHY DETECTION IS IMPORTANT
ROTOR UNBALANCE
VIBRATION
HIGHER FIELD CURRENT IS REQUIRED
HIGHER TEMPERATURE WILL RESULT
DIMINISHED CAPACITY

COMPARISON[/ ....etc
