RT25 | Testing Protection Functionalities of IntelliRupter Fault Interrupter with OPAL-RT HiL Testbed

Jiahao Xie from S&C Electric Company presents a Hardware-in-the-Loop (HiL) testing framework integrating IntelliRupter fault interrupters with OPAL-RT’s simulation systems. The study validates protection features such as PulseClosing, PulseFinding, Intelligent Fuse Saving (IFS), and Communication-Based Coordination (CEC), demonstrating realistic power system interactions and streamlined test automation for advanced distribution protection.
