State-of-the-Art Prototype Testing of PAC Devices for the Power Industry

Protecta Electronics Ltd., a leading Hungarian manufacturer of digital protection relays and automation products, has significantly enhanced its real-time testing capabilities through the integration of OPAL-RT’s advanced technologies. At the heart of this solution is ARTEMiS, OPAL-RT’s powerful solver for electromagnetic transient simulation, which, alongside the OP4510 real-time simulator and RT-LAB software platform, enables seamless execution of MATLAB Simulink® models in real-time. This setup supports precise and automated Hardware-In-the-Loop (HIL) testing for protection and control devices, including complex controller functions and coordination across multiple IEDs. The result is a flexible, scalable, and high-precision testing environment that meets both international standards and customer-specific requirements. With this innovation, Protecta has streamlined its R&D processes, accelerated accreditation for global markets, and is now expanding into advanced scenarios such as busbar and line differential protection, further solidifying its role as a pioneer in power system protection solutions.
