SCADA, RTUs and PLCs
Most of digital control systems use a Supervisory Control And Data Acquisition (SCADA) with Remote Terminal Unit (RTU) for monitoring the metering devices for incoming and outgoing feeders.
Beside SCADA and RTUs digital control systems use a Programmable Logic Control (PLC) technique for controlling and monitoring the system inside substations by professional engineers.
Then the data from each RTU will be send to the SCADA (main Computer) via special router, the SCADA system used ION enterprise software supplied by AREVA company in addition to all panels which supplied by the same company.
Many difficulties were appeared during the work, such as mistakes of IPs, setting parameters, selection of protocols, and matching of devices have solved until the normal work was obtained to the substation.
How it works?
SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining and transportation.
These systems encompass the transfer of data between a SCADA central host computer and a number of Remote Terminal Units (RTUs) and/or Programmable Logic Controllers (PLCs), and the central host and the operator terminals.
A SCADA system gathers information (such as where a leak on a pipeline has occurred), transfers the information back to a central site, then alerts the home station that a leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion.
These systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or very complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system.
Traditionally, SCADA systems have made use of the Public Switched Network (PSN) for monitoring purposes. Today many systems are monitored using the infrastructure of the corporate Local Area Network (LAN)/Wide Area Network (WAN).

I hope you are doing well, can you send me latest updates for SCADA, PLC, DCS and Industrial Automation.
I want to ask about connections of SCADA & RTU monitoring ,
is this necessary Motorized breaker is only applicable to SCADA and RTU.
Since our PSS main breaker is not Motorized what is our options to utilized SCADA & RTU monitoring system
your reply is very helpfull
Can you send SCADA Substation installation testing & commissioning procedures
I am electrical engineering graduate and find a job in core so please help me to find the job
pleas,explain clearly about the operation of per phase transformer
