This project will purchase the equipment required to perform condition monitoring of the specific type of bushings and Instrument Transformers (ITs), this wasn’t possible before with current technology in use within the industry. This is innovative because the method will create a solution using existing off the shelf technology, and combine it in a new way to give the desired condition assessment tools. 

This is a first proof of concept where the innovative aspect is bringing together several technologies in an integrated way with remote communications.

The objective of the project is to develop a novel integrated solution for condition monitoring on bushings and Instrument Transformers. Then, we need to test the solution to see how effective it is. Lastly, we will develop an implementation procedure to ensure the solution gets fully implemented into the business.
