A Visionary New Tool for Dynamic Transient Testing PSCAD/Relay and associated test equipment represent the next generation of relay testing. PSCAD/Relay is a time-based power system simulator that generates test waveforms with the same real world fidelity as events recorded from the power system itself. PSCAD/Relay, can be utilized to test the protection system, using the same signals the system will see. The result is more accurate and more realistic protection testing. The test waveforms are generated in a powerful interactive simulator , taking less time and producing superior results compared to traditional methods.Personnel responsible for relay testing do not have to make assumptions about which waveform characteristics are important for proper relay operation. Real system events, such as current reversal on parallel lines, are easily produced. Faults can be applied at any point on the cycle. Different operating times for breakers, DC offsets, inrush, mutual coupling, resonance, harmonics, and saturation effects are all included. Batch mode simulation allows for a series of test waveforms to be developed quickly and efficiently . Advance and speed up your testing process. Eliminate false operations before they occur.
