What is SCADA? : 

February 7, 2007 8th IIEE-CSC Annual National Student Convention 4 What is SCADA? A Supervisory Control and Data Acquisition System is a two-way computerized system for real-time control, monitoring and supervision of remote devices; typically from a continuously manned, central location.

Slide 5: 

February 7, 2007 8th IIEE-CSC Annual National Student Convention 5 What is SCADA? A Supervisory Control And Data Acquisition (SCADA) System performs the traditional supervisory functions such as the gathering of data and performance of control functions. SCADA provides system operators with state of the art tools for a well-informed decision in operating remote substations. System operators are able to focus-in on problem areas quickly because real time data is summarized in integrated displays. The high data security/accuracy inherent in the system, allows operators to make decisions and take corrective action with utmost confidence.

What is Distribution Automation(DA)? Without DA, utilities will do the same tasks manually through system operators and field crews. DA functions address inherent needs of the electric system. Thus, they outlive changes in technology. However, DA devices are affected by changes in technology.
