The Megger FREJA 546R Relay Test System brings strong performance and flexibility into a compact, field-ready unit. It delivers up to 60 A per phase with a flat power curve, which allows reliable testing under demanding conditions. The system includes four voltage channels and three current channels, and you can convert these to six currents when needed. This flexibility supports a wide range of protection schemes, including differential testing. It also handles dynamic and transient testing, while GPS synchronisation keeps timing accurate during end-to-end tests. IEC 61850 support ensures smooth operation in modern substations. You can work directly from the large touchscreen for quick manual checks, or connect to a PC for automated testing and reporting. Overall, the FREJA 546R helps simplify complex relay testing and improves efficiency in both field and workshop environments.
