Abstract
In this project, we discuss condition monitoring of insulation for electric machines. This topic is very important for the Oil/Gas industry because of its aging electric power generators. Specifically, the Oil/Gas industry experiences long stoppages of its power generation units for re-winding, during a time when power is extremely needed. In addition, these fixed-interval scheduled maintenance practices are very costly as on average they cost around US$1 million per 11 KV generator. To address these problems, we propose an effective, reliable and automatic technique to monitor the insulation condition of electric
