A Visionary New Tool forDynamic Transient Testing
PSCAD/Relay and associated test equipment
represent the next generation of relay testing.PSCAD/Relay is a time-based power systemsimulator that generates test waveforms with thesame real world fidelity as events recorded from thepower system itself. PSCAD/Relay, can be utilized totest the protection system, using the same signalsthe system will see. The result is more accurate andmore realistic protection testing.
The test waveforms are generated in a powerfulinteractive simulator, taking less time andproducing superior results compared to traditionalmethods.Personnel responsible for relay testing do
not have to make assumptions about whichwaveform characteristics are important for properrelay operation.
Real system events, such as current reversal onparallel lines, are easily produced. Faults can beapplied at any point on the cycle. Differentoperating times for breakers, DC offsets, inrush,mutual coupling, resonance, harmonics, andsaturation effects are all included. Batch modesimulation allows for a series of test waveforms tobe developed quickly and efficiently.
Advance and speed up your testing process.Eliminate false operations before they occur.
