In the electric power system, distribution network plays a vital role in power distribution. There is numerous distribution transformers (DT) present in the distribution network. DT should be operated carefully for the effective distribution of electricity to the loads. The cost of DT is very high. So its lifetime is extended by proper monitoring that greatly useful in the electricity delivery in vast distribution system without any installation of new transformer. The condition of DT is assessed by monitoring various parameters include load current, over voltage, oil level and oil temperature. As the implementation of transformer condition monitoring system through the Internet of Things (IoT) connects Micro Controller Unit (MCU) interfaced to sensors and motor with Wi-Fi modem. This designed system is fixed to the transformer. The parameters values are collected by sensors and circuit are recorded by the MCU and displayed on the LCD. The data is communicated to the server webpage through Wi-Fi module by the MCU periodically. The server is designed to check for unusual condition in the DT. Then the server will send Short Message Service (SMS) to designated mobile phone of the lineman if there any unusual condition exists in the transformer. Automatically oil is filled to the transformer by using the motor when the oil level low is noticed as unusual condition. This system is useful in optimizing the transformer operation and reduces the manual labour. It is the improved system for transformer monitoring to prevent DT from catastrophic failure.
