Megger FREJA549 Relay Test System
The Megger FREJA549 relay test system is a versatile, lightweight, and portable device designed for secondary testing of protection relays. It provides up to 9 current channels and can be operated manually using the built-in touch screen interface running FREJA Local, or fully controlled by a computer through FREJA Win Software. The integrated user interface is Megger’s second generation of automatic/semi-automatic manual interfaces.
The FREJA549 features high compliance voltage for testing high impedance earth fault relays and high current capabilities to test all types of overcurrent relays, including electromechanical, solid-state, and numerical-based. It also handles voltage-controlled, voltage restraint, and directional overcurrent relays.
