SEL Distribution Network Automation

The SEL Real Time Automation Controller (RTAC) is well known as a substation RTU, Data Concentrator and HMI for complete substation control and monitoring.

SEL Engineering Services have also developed a Distribution Automation Controller (DAC) Library which provides excellent control of automatic network reconfiguration, coordination preservation with reconfigured networks, volt/var control, var support, control of inverter-based generation, centralized control/engineering access, fault location and automated event collection.

Please talk to your local APS salesman about your needs and plans for Distribution Automation Schemes!

SEL Wireless Fault Indicators

Your distribution automation system can also be enhanced with the new wireless 
fault indicators from SEL – the high speed FT50/FR12 for protection applications 
or the SCADA data you can collect from the FLT/FLR.

Either product utilizes unlicensed 900Mhz communications from the fault indicator to a receiver over distances of up to 4 miles for the FT50 or up to 10 miles for the FLT.

SEL-FLT Wireless Fault Indicator/SEL-FLR 
Ethernet Receiver

The FLT/FLR utilizes DNP over Ethernet to communicate to your SCADA system. Up to 192 FLT fault indicators communicate to one FLR receiver and provide fault indication, load current accurate to +/-2%, as well as fault current. The FLT also provides visual indication to linemen similar to the SEL AR360 fault indicator.
