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.
