The solutions for testing relay protection SMRT (Smart Relay Test System) by Megger showcases the technological edge in diagnostics for modern electro energy systems, combining uncompromising power with remarkable comfort for the user. In the age where the stability of the electrical grid is critical for the infrastructure, these devices ensure reliable work for networks, by allowing precise checking of complex protection mechanisms at mountain substations, industrial environments and installations for renewable energy.

"Relay protection specialists often face the challenge of balancing stringent laboratory requirements with harsh field conditions. Megger addresses this issue by incorporating patented high-power signal generation technologies into the lightweight, impact-resistant housings of the SMRT test system, making it an indispensable standard for power utility maintenance worldwide," representatives from Megger informed BalkanEngineer.com.

Thanks to their flexibility, the SMRT systems by Megger allow for tests for old relays, as well as the new generation of digital relays. “At the heart” of every configuration are the patented VIGEN modules, which redefine the idea for flexibility in electrical equipment. "This technology allows users to combine power sources into a single physical unit based on the specific needs of the site, with the software automatically recognizing and calibrating the new hardware topology. Each individual module operates as an independent source with high phase accuracy, enabling channels to be connected in parallel to achieve extreme current amplitudes or in series to generate the high voltages required for specific earth fault protection applications," Megger commented.
