Remote monitoring of power system apparatus in the context of smart grid

This paper discusses the details of designing and building a monitoring system that can be used to evaluate the status of power system apparatus remotely. The monitoring system was built and tested to monitor both the partial discharge inside a transformer model and the leakage current on an outdoor insulator´s surface. The monitoring system is designed to measure different parameters and hence to evaluate the status of the power system apparatus and display them in real time. Moreover, the system will also send email notifications which keep the utility engineer informed regarding the status of the power system apparatus at all times.
