Application of GSM Technology for Fault Identification and Categorization in Three-Phase Transmission Line

The primary objective of this research paper is to detect faults in electrical transmission line parameters and transmit this information in real time via the Global System of Mobile Communication network (GSM) to the Electricity Transmitter Station. This work attempts to continuously check the voltage of the transmission line that will be transmitted. If the voltage exceeds the predefined rated capacity, the microcontroller will shut down the line and notify the operator via a GSM modem and the LCD (Liquid Crystal Display). The modem serves as a communication interface. It uses a serial interface to transparently transfer device protocols across the network. If the operator needs to know the voltage and temperature at any time, there is a local display that can show the information.
