IOT Based Transformer Health Monitoring System: A Survey

The transformer is playing a vital role in the electrical power grid. As it deals with high voltage and current which can greatly affect the functioning and physical condition of the device, continuous monitoring has become an integrated part of its operation. This paper presents a review on IoT (Internet of things) based electrical parameters monitoring and controlling technology to avoid its successive catastrophic failures. Here, different sensors and server models are used for communication, mostly used is GSM-GPRS. In case of some abnormality, this advanced monitoring system will deliver a message to a dedicated device for further course of action. The work done in recent few years in the field of parameter monitoring using the internet is discussed here.
