How SCADA Controls Entire Factories and Power Plants — Explained Clearly

SCADA is the hidden control system behind modern factories, power plants, substations, water systems, pipelines, and industrial automation. In this engineering documentary, we explain SCADA clearly from the beginning — including its history, components, sensors, PLCs, RTUs, HMIs, communication protocols, alarms, historian data, cybersecurity, and real industrial examples. You will understand how SCADA collects data, displays live plant conditions, sends supervisory commands, records trends, generates alarms, and helps operators control massive industrial systems from one control room. This video is useful for engineering students, electrical engineers, instrumentation engineers, automation engineers, plant operators, maintenance teams, and anyone interested in industrial control systems.
