IoT Based Transformer Monitoring and Control

Distribution transformer is the most vital asset in any electrical distribution network and therefore it needs special care and attention. Transformer failure mostly occur due to excessive load which leads to unexpected power shutdown. To overcome this shutdown due to overload we proposed a system for monitoring the transformer load current. Faults which can result in loss of service and are costly to repair can be monitored by this system before they occur. An Embedded based hardware design is developed to acquire data from sensing system. It consists of a sensing system, embedded hardware for middle level computing. A powerful GSM networking is designed to send data from a microcontroller to android app for proper action. System is programmed with some predefined instructions to check abnormal conditions. Optimal utilization of distribution transformer by its utilities can be brought into reality by implementing this system. Here controller is continuously reading the load current, and display on the LCD along with the set point. If current value is crossing the set point then supply will turn off; control action is based on the set point.
