SEL Advanced Digital Fault Recorder Solutions

Comprehensive substation data collection, monitoring, and visualization

SEL advanced digital fault recorder (DFR) solutions represent the next generation of substation data collection, monitoring, and visualization. Leverage a wealth of data to investigate disturbances, monitor substation assets, and exceed compliance with standards such as NERC PRC-002.

Versatile and Reliable

SEL advanced DFR solutions combine the powerful logic engine of the SEL Real-Time Automation Controller (RTAC) with the modular Axion I/O platform. Our solutions capture event reports at 24 kHz with 24-bit resolution and submicrosecond accuracy. They also record dynamic disturbance data at 250 Hz for more than 30 consecutive days, log Sequence of Events (SOE) data with 1 ms accuracy, provide impedance-based fault locating, and support many advanced applications.

Configure in Minutes

With a streamlined DFR configuration interface, acSELerator RTAC SEL-5033 Software allows you to quickly and easily configure your DFR solution. Enter settings in a simple form to build your system within minutes.

Capture Every Disturbance

SEL advanced DFR solutions can stream and record continuous oscillography data at 3,000 samples per second. With 2 TB of storage, you can record locally for at least 10 consecutive days, so you never miss a system disturbance. This also allows you to exceed compliance with standards such as NERC PRC-002—even without configuring triggers.

With this resolution of continuous data, the solution can also automatically calculate and record energy packets for more precise measurement of energy flow under all system conditions.

Live continuous oscillography data streaming from the Axion to Synchrowave Monitoring visualization software.

Monitor Substation Assets and Networks

SEL advanced DFR solutions offer extensive asset monitoring capabilities that help you proactively manage your system. The flexible RTAC logic engine has tools and libraries available for monitoring CTs and PTs for impending failures, collecting breaker wear reports, auditing substation networks, and more.
