1. Electricity Generation, Transmssion, and Distribution Systems:
- SCADA systems are used in electric power generation plants, transmission areas, and distribution systems.
- SCADA systems monitor each and every phase of the generation of electricity from fuel input to electrical output.
- SCADA systems can also be used to monitor and control electrical switchboards, Grids, and transmission lines.
- SCADA monitors and controls the actual electrical power being transmitted over long distances.
- This system responds to load fluctuations instantaneously.
2. Manufacturing Industries or Plants:
- A SCADA helps in managing various raw materials or inventory items, to control automated systems in synchronous order.
- SCADA precisely controls every plant operation to ensure all systems run smoothly and meet productivity targets.
- SCADA tracks the number of units produced, & measures process values such as temperature, pressure, and humidity at various production phases.
- It also controls assembly line robots.
3. Food & Pharma Production:
- SCADA system monitors and controls all stages of the production unit.
- Controls the exact mixture of required ingredients.
- Monitors the time and temperature required to manufacture & process food & beverages or pharmaceutical products.
- SCADA documents data to prove the production meets the industrial standard and government regulations.
4. Telecom & IT-based systems:
Managing different Radio Frequency based systems, communication mediums, and large communication systems such as logging data and information through an antenna using a SCADA system is very easy.
5. Water Treatment Plants, Sewage Treatment Plants, & Supply Management:
- Municipal Corporations and other government sectors are using SCADA for monitoring, controlling, and regulating the level and flow of water in dams & reservoirs.
- SCADA system monitors and controls the water being pumped from bore wells and treated at WTP.
- This system controls flow rate sensors and contaminant sensors.
- This controls the booster pump to regulate the water pressure supplied to the process.
6. Traffic Controls:
- In metropolitan cities, SCADA regulates traffic signal lamps, detects signals out-of-order, & controls traffic flow.
- In railway systems, on-road systems, & airlines the traffic flow is controlled by the SCADA system.
7. Lift & Elevator Controls:
SCADA system can also be used to lift and control elevators in commercial malls and in large industries.
8. Buildings & Society Environments:
Facility managers use SCADA to control High Voltage AC, refrigeration units, lighting, and entry systems.
9. Oil & Gas Systems:
