In order to mitigate the cost of manpower and resource in maintenance of power distribution assets, and to deal with the inefficiency caused by the separated protection / automation system and maintenance / management system , a 4-in-1 intelligent terminal unit is proposed, which combines the functions of protection, measurement and control, online monitoring, and maintenance. It covers all the functions of a conventional distribution automation terminal unit and additionally provide maintenance functions based on multi-dimensional analysis to the online monitoring data collected through multiple sensors for temperature, mechanical characteristics, contacts movements, etc.
