Monitoring Process.
•Feature extraction of insulator
•Condition analysis of insulators
1..Feature extraction
•Done by using wavelets multi resolution analysisThe wavelet transform is given by…
C – Wavelet transforma – Wavelet scalef – Wavelet positionφ – Wavelet function
Mother wavelets used..
•Impimentation of DWT through sub-band coding
2..Condition analysis
Condition indices
obtained from
SVM (I)
Conclusion
Advantages:-•Improves efficiency.•Gives flexibility.
Disadvantages:-•Instalation of cameras.•Can’t account non visual defects.
Scope of further study
•Usage of thermal cameras instead.
