Abstract: The goal of this project is to collect remote electrical characteristics such as voltage, current, and frequency, and to send these real-time values, together with the power station temperature, over the GSM network using a GSM modem / phone. This project also includes the use of an Electromagnetic Relay to protect the electrical circuits. When the electrical parameters surpass the predefined values, this Relay is activated. This system can also provide real-time electrical parameters as SMS messages on a regular basis (depending on time settings). Electrical characteristics such as current and voltage will be compared to their rated value on a regular basis to safeguard the distribution and power transformer from overload, short circuit faults, overvoltages , and surges. Under such circumstances, the entire device is shut down, with transfers detecting it and the electrical switch being killed instantly. This project takes use of a microcontroller, which is a type of onboard computer. This internal computer is capable of communicating effectively with the many sensors in use. The substation becomes intelligent as a result of the usage of GSM, since it is able to communicate alarms and information as well as accept commands.’
