SCADA for Substations

How new technologies can improve monitoring and control

BY LOURENCO TEODORO, InduSoft

Substations are a critical component for maintaining electrical supply and load control in low voltage, medium voltage and high voltage electrical distribution networks. In order to ensure the proper functioning of substations and related equipment such as line-mounted switches and capacitors, most utilities use SCADA (supervisory control and data acquisition) systems to automate monitoring and control.

New sites typically implement a SCADA system to monitor and control substations and related equipment. However, older facilities can also benefit by adding a SCADA system or by upgrading an existing SCADA system to take advantage of newer technologies.

Not only will a new or upgraded SCADA system provide better monitoring and control, it can also extend the life of substations and related equipment by providing current data for troubleshooting small problems before they escalate. Furthermore, the ample historical data provided...
