Condition monitoring of outdoor polymeric insulation structures using wavelets and neural networks
Tracking studies were carried out under AC and DC voltage, with EPDM specimens following IEC-587 standards. It is observed from the experimental study that the increase in conductivity, flow rate and the applied voltage reduces the tracking time of the material. In the present work, use of multi resolution signal decomposition technique and the artificial neural networks to monitor the surface condition of the insulation structure under AC voltage was demonstrated.
