A smart IOT based system for monitoring and controlling of distribution transformer(VTU, Belagavi)

To maintain the reliability in grid operation it is important to monitor real time transformer health. We know the importance of transformers in electricity distribution and transmission. They are the main components and constitute the large portion of capital investment of the distribution grid. Real time transformer health monitoring systems help to replace the equipment before failure and continuity of the power will not be disturbed.

Why its important to develop IoT Based Transformer Monitoring System?

To understand this we need to find the drawbacks of the conventional transformer monitoring system and the biggest problem in the electricity distribution grid.

• Most of the distribution transformer are remotely located in a rural area, where regular monitoring by human observation is difficult to perform due to insufficient manpower.
• Our existing monitoring systems are not supported for real time operations. There is to many transformer failure cases are detected every day.
• Not allowed for planning operation downtime.
• Coventional system Don't have nay internal fault testing [incipient fault monitoring]
• To overcome the above drawbacks we need a smart and reliable

solution to monitor the distribution transformer parameter and send it to the IoT platforms in real time. It enables the grid operator to define the performance of the unit. It also provides important information about transformer health. IoT Based Transformer Monitoring System will allow the utilities to optimally run the transformer and keep this equipment in operation for a longer period.

The important parameter we needs to monitor:

• Transformer Temperature
• Oil Level/li>
• Oil Quality
• Current level
• Voltage level
• Humidity
• KVA and Power Factor
• Incipient fault monitoring
