Analyze Relay Event Data—Plot relay oscillography, display phasor magnitudes and angles, and monitor digital status. Navigate through events with integrated zoom and pan functions.
Time-Align Event Reports—Easily coordinate multiple event report times for accurate comparison and analysis of signals from multiple relays or past event reports.
Perform Calculations—Create equations to analyze specific trip conditions. Instantly plot calculation results for quick event analysis. The built-in function library creates endless calculation possibilities.
COMTRADE Viewer—View COMTRADE reports from a variety of sources together in synchroWAVe Event for complete COMTRADE file analysis.
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.
Advanced Fault Location Visualization—The SEL-411L Advanced Line Differential Protection, Automation, and Control System, the SEL-T400L Time-Domain Line Protection, and the SEL-T401L Ultra-High-Speed Line Relay 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.
Plot relay oscillography, display phasor magnitudes and angles, and monitor the digital status. Navigate through events with integrated zoom and pan functionality.
Drag cursors throughout the event report to compare measurements.
Quickly add analog and digital signals to charts by filtering signals as you type in the search bar.
Create equations to analyze specific trip conditions. Instantly plot calculation results for quick event analysis. The built-in function library creates endless calculation possibilities.
Easily coordinate event report times for accurate comparison and analysis of signals from multiple relays or past event reports.
Load a new event report, or add an event report to the current analysis session. Event COMTRADE, compressed ASCII (.CEV), event report (.EVE), and traveling-wave file formats are supported.
Analyze 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.
Quickly turn on and off each of the distance element zones.
Drag 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 distance element as the relay sees it. Observe how the mho circle characteristic moves in response to changes in the polarizing voltage.
Easily adjust the line length based on updates from the field. Use multiple peak locations to adjust the wave propagation speed to compensate for line sag, air temperature, and humidity. Feed this information back into relay settings for improved relay operation.
See the traveling-wave arrivals detected by the SEL-T400L, SEL-T401L, or SEL-411L at the terminal. The Bewley diagram shows the traveling wave’s propagation path along the transmission line and reflections from fault and line terminals.
The fault location is represented by the vertical gray bar. From this point, traveling waves are launched in each direction.
Easily import and coordinate traveling-wave event reports from SEL-T400L, SEL-T401L, or SEL-411L relays on both ends of the line. Remove fault location ambiguity, and have more freedom when choosing which signals to use for compensation to the wave propagation speed.
Visualize the pulse propagation through the fault after reflecting off a terminal. The strength of through-fault pulses gives an indication of the fault strength when only single-ended fault data are available. The timing of a pulse arrival after propagating through the fault enables the adjustment of the wave propagation speed.
