FREJA™ 306 is the latest member of the relay testing equipment from Megger, quick and easy to use, like the FREJA 300. The rugged hardware design is built for field use over a wide temperature range, with the possibilities of intelligent software to perform rapid testing.
FREJA 306 can be operated with or without a PC. After being put into the Local mode, FREJA 306 can be used stand-alone without a PC. Using the Local mode is easy. FREJA 306 is an excellent choice when you want more current outputs, higher amps (3 x 15 A + 3 x 35 A), VA or compliance voltage. Use it to test differential relays with 6 currents, or virtually any single or 3-phase relay. When testing 1-phase relays, you can make use of either the high current (over 100 A), or the very high compliance voltage. This now makes it possible to test high impedance relays of different kinds, like rotating disc relays, earth protection relays, etc.
FREJA 306 can be also be used as a fault simulator to ensure proper relay configuration for specific applications. This is possible by importing and re-generating transient disturbance files often referred to as COMTRADE files. These files may include calculated digital records created by power network simulator software’s such as EMTP, RTDS or data records from actual fault events. With the built-in DC source you can directly supply the protection relay
