Visualize Distance Elements
Analyze protective relay distance element operation with the exact mho circle diagram. The mho circle diagram enables plotting apparent impedance and distance element characteristics for analysis.
Save Analysis Setup Time
Create personal and relay specific analysis templates to provide a customized view into the relay’s operation. Save and share templates for more efficient post-event analysis.
Understand Differential Element Performance
View the current differential ratios plotted directly onto the complex alpha plane. Supporting both two- and multi-terminal lines, you can overlay the differential ratio with the restraint region to quickly identify when the differential element picked up. Experiment with alternative restraint regions to explore the effects of alternate protection settings.
See Traveling Waves
Advanced Fault Location Visualization—The SEL-411L Advanced Line Differential Protection, Automation, and Control System, the SEL-T400L Time-Domain Line Protection, the SEL-T401L Ultra-High-Speed Line Relay, and the SEL-TWFL Dual Traveling-Wave Fault Locator and 12-Channel MHz Recorder can record traveling-wave data to provide highly accurate fault locating. Synchrowave Event generates a Bewley lattice diagram from the traveling-wave data to enable visualization, analysis, and understanding of the traveling waves recorded for an event.

- Mho Circle AnalysisAnalyze distance element operation with the mho circle diagram. The mho circle diagram provides an impedance plane on which to plot apparent impedance and distance element characteristics.
- Choose your zoneQuickly turn on and off each of the distance element zones.
- Pinpoint the impedanceDrag the cursor throughout the event to see the apparent impedance. The yellow dot indicator shows you where the impedance is on the plane.
- See the mho characteristic moveSee the distance element as the relay sees it. Observe how the mho circle characteristic moves in response to changes in the polarizing voltage.

- Refine parametersEasily adjust the line length based on updates from the field. Use multiple peak locations to adjust the wave propagation speed or wave propagation travel time to compensate for line sag, air temperature, and humidity. Feed this information back into relay settings for improved relay operation.
- Pinpoint the reflectionSee the traveling-wave arrivals detected at the terminal. The Bewley diagram shows the traveling wave’s propagation path along the transmission line and reflections from fault and line terminals.
- Identify the fault pointThe fault location is represented by the vertical gray bar. From this point, traveling waves are launched in each direction.
- Locate faults with a double-ended methodEasily import event records that contain traveling-wave data from both ends of the line. Slide the time cursors to line up with the peak of the initial traveling wave that arrived at each line terminal to obtain a highly accurate fault location. Optionally, fine-tune the results by placing additional time cursors on traveling waves that arrived at each terminal after reflecting from the fault or opposite terminal.
- Locate faults with a single-ended methodVisualize the traveling wave propagation through the fault after reflecting off a terminal. The difference in arrival times between the initial traveling wave at the local terminal and the first traveling wave that was reflected from the fault can be used to locate the fault using a single-ended method. The arrival time of a traveling wave that reflected off the remote terminal and propagated through the fault enables the adjustment of either the traveling wave propagation speed or propagation time.
