Purpose and necessity development

A system for comprehensive prevention diagnosis of power
facilities by attaching a number of sensors to transformers and
GIS for partial discharge, breaker operation characteristics,
bushing diagnosis, etc. and analyzing data acquired online
comprehensively to diagnose facility abnormalities.
