As the complexity of distribution network has grown, automation of substation has become a need of every utility company to increase its efficiency and to improve the quality of power being delivered. The proposed project which is IOT based controlling of the substation will help the utility companies, by ensuring that their local-substation faults are immediately realized and reported to their concerned departments via IOT, to provide that term of intensity intrusion is decreased. The measured parameters will send as SMS messages. The microcontroller will cooperate with the sensors introduced at the nearby substation and perform a task as commanded. Electrical parameters like current, voltage will be compared continuously to its rated value will help protect the distribution and power transformer from burning due to overload, short circuit fault, overvoltage’s, and surges. Under such conditions, the whole unit is closed down through the control area including transfers detecting it, and instantly killing the electrical switch. SMS cautions can likewise be produced to demonstrate this. The utilization of GSM makes the substation astute in the sense that it can transmit signals and information and receive commands. This enables to reduce labor cost at the substation and spares time. In this manner, the observing and working effectiveness of the sub-station will definitely increment. © 2019 Elsevier B.V., All rights reserved.
