Introducing Our Principal Engineers’ Talk at PSCAD UGM 2023, Boston!
Join us at PSCAD UGM 2023 in Boston, where our Principal Engineers will unveil a compelling case study. A load break switch’s unexpected failure during a vital task led to an extended arcing event, triggering a single line-to-ground fault. Using PSCAD/EMTDC simulation, we examined the interrupter’s transient recovery voltage (TRV). In a restrike scenario, the transient current surged to 1000 A, and the peak line-to-ground voltage spiked to 2.20 p.u. Notably, the computed TRV reached 536 kV post-restrike, surpassing the interrupter’s 480 kV TRV capability rating.
This study highlights two key recommendations:
- Enhanced Operational Protocols: For interrupters without capacitive switching ratings, review and refine switching procedures.
- Empowering Line Charging Interruption: Explore interrupters with capacitive current interruption capabilities to handle unloaded transmission lines.
