Online Transformer Monitoring System

Power transformers, are basically used for stepping up& down the voltage levels. They primary equipment in power transmission system. So it is to maintain all transformers located geographically, but due lack of man impossible monitor regularly. Due these reasons, if a failure occurs transformer may cause network shutdown. Though there lot protection measures that accompany transformer, by providing online monitoring system will increase reliability and reporting instantaneous fault confidently. This paper gives out details design construction an automatic parameters. A node-mcu module [esp8266] was enabled voltage, oil level temperature (oil & winding) on typical transformer. With internet things (IoT), self-defense designed implemented In this Transformer parameter continuously marked graph plotted. If increases than actual value, buzzer alarm, no action taken then whole be tripped safely transformers.
