Impedance test system FREJA549

for electrical machines and installationsthree-phase relayportable

• Provides up to 9 currents for testing transformer and bus differential relays • Fully automated testing using FREJA Win software • Standalone operation using intuitive high resolution graphic touchscreen, no PC required to operate • 4 voltage channels, 3 current channels, with convertible voltage channels providing 1 voltage and 6 currents • High current, high power output – up to 60 Amps/300 VARMS per phase • Dynamic GPS satellite synchronised end-to-end testing ability • IEC 61850 testing ability The FREJA 549 relay test system is a multipurpose, light, portable test instrument designed for the secondary testing of protection relays. Offering up to 9 current channels, the unit can be operated either manually via the built-in touch screen user interface running FREJA Local, or placed under full computer control via the FREJA Win Software. The built-in user interface is Megger’s second generation of automatic/semi-automatic manual user interface. The FREJA549 has high compliance voltage to test high impedance earth fault relays, and high current to test all electromechanical, solid-state and numerical-based overcurrent relays, including voltage controlled, voltage restraint, and directional overcurrent. The large, easy to read full colour high resolution, high definition, TFT LCD touch screen display allows you to perform manual, steady-state, and dynamic testing quickly and easily. FREJA Local includes built-in preset test routines for automatic testing of protection relays and protection schemes. Menu screens and touch screen function buttons are provided to quickly and easily select the desired test function.
