The Megger FREJA 549 Multi-Phase Relay Test System delivers impressive flexibility for advanced protection testing. It provides up to 60 A per phase with a flat power curve, which ensures reliable performance under load. The system includes four voltage channels and five current channels, and you can convert these to nine current channels when required. This setup supports complex schemes such as differential and multi-ended protection testing. It also performs dynamic and transient testing, while GPS synchronisation keeps timing accurate across remote locations. IEC 61850 support allows seamless testing in modern digital substations. You can operate the unit directly using the large touchscreen for fast manual checks. Alternatively, you can connect to a PC for automated testing and detailed reporting. Overall, the FREJA 549 gives engineers a powerful and efficient tool for demanding relay testing tasks.
