Supervisory control and data acquisition (SCADA) is used, as the name suggests, to monitor and control processes. My personal exposure to SCADA was while working for the Potomac Edison power company in Hagerstown, Maryland, as an engineer. for a short time right after graduation from college. At the time, all of the substations and big switching stations either had, or were being outfitted with SCADA capabilities. Functions ranged from simple monitoring the positions of circuit breakers and power (voltage & current), to changing transformer tap ratios and operating switches. Remote communications were handled via telephone model or power line carrier. Some work was being done with wireless. Of course SCADA implementations have much wider and varied uses than power distribution. Vast manufacturing installation and industrial process are handled through SCADA.
