ABSTRACT
Supervisory control and data acquisition communication (SCADA) refers to the communication channels employed between the field equipment and the master station. The channel makes it possible for a remote control center to access the field data in real time for assessing the state of the system, whether the generation by each unit, the voltage and current vectors from buses, the loading on the system, or circuit breaker and isolator positions. Distribution systems were minimally automated, and at the most, monitoring was performed at substations for sending the data to higher hierarchies. The digital data from a device are to be communicated to another device via some physical medium, and for this purpose, the digital data are first converted to a digital signal for transmission. SCADA communication is analogous to the nervous system of the human body which runs from the brain to every part of the body transporting data and signals back and forth continuously.
