4. A REVIEW ON GSM BASED TRANSFORMER HEALTHCARE MONITORING WITH OVERLOAD ALERT

A crucial component of the transmission and distribution system are transformers. Monitoring transformers for issues early on can help avoid faults that are expensive to fix and cause a loss of service. Although current systems can give information about a transformer's condition, they are either offline or extremely expensive to implement. This study presents a novel method based on remote transformer monitori ng system employing PIC Microcontroller and GSM technology. Transformer condition monitoring remotely using a variety of methods is already well-known and used. The monitoring is mostly carried out to reveal significant parameters that reflect conditions of transformers, such as increase or decrease in oil level, over voltages, over currents, and increase in winding temperatures. Also the GSM modem used is a two way communication d evice, so the mobile user can any time know the condition of the transformer parameter by simply sending message to the modem.
