Health condition monitoring system for distribution transformer using Internet of Things (IoT)

Electrical transformers are the important elements in the process of transmission and distribution of electricity. Transformer is one of the important and costliest components of electrical industry. As we know, Distribution Transformer is a major component of power system and it's correct functioning is vital to system operations. This paper presents the development of a mobile embedded system, to monitor and record parameters of a distribution transformer like Current, Temperature, Rise or Fall of Oil level, Vibration and Humidity. Remote terminal unit is installed at the distribution transformer site and above parameters are processed and recorded using-in-8-channel analog to digital converter (ADC) of the embedded system in the system memory. If any abnormality occurs, the system sends alert messages to the mobile phones as well as monitoring units which containing information about abnormality to some predefined instructions programmed in the microcontroller. Also it is important to keep an eye on transformer health when operator is not present at transformer site, so we are introducing embedded system named as two way communication systems between transformer and operator. This system is designed to send alert messages, whenever related parameters value exceeds the predefined limits. This system proposes a compact design and development of remote monitoring system, for a distribution transformer. The main objective of this project is to develop mobile embedded system will help the utilities to optimally utilize the protection of power line of transformer and identify problems before any catastrophic failure.
