Real Time Monitoring & Controlling System for Distribution Transformer

This paper presents a GSM technique for monitoring and controlling the distribution transformer. In the substation SCADA system is used for protection of transformers. But when feeders come out after substation there is no any protection system in distribution. The number transformers in the distribution system are very large and it is very difficult to proper manual maintenance. So this paper presents a method of monitoring and controlling for distribution transformers. In this method monitoring on voltage, current, temperature of transformer and oil level in the tank of transformer. The data from sensors sent to Arduino where it compares the preset and real time parameters, if parameters value exceeds the alert message through GSM for particular number of transformer. If parameter value exceeds beyond particular value, command for controlling transformer is given. This method gives advantages for continuous monitoring, proper alert to detect fault, so the life of transformer increases.
