Programma FREJA 300 Relay Test System Megger Relay Test Set

The FREJA™300 relay testing system is a computer-aided relay
testing and simulation system. The weight of FREJA 300 is only
15 kg. 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 300 can be operated with or without a PC. After being put
into the Local mode, FREJA 300 can be used stand-alone without
a PC. Using the Local mode is easy. The function of each key
is described on the display, which also presents the settings and
measured values.
The very accurate (typically 0.01%) low level analogue inputs are
designed for transducer measurements. The high level inputs can
be used as a normal volt- and ammeter. FREJA 300 can generate
4×150 V (82 VA) and 3×15 A (87 VA) or 1×45 A (250 VA). Each
output can be varied independently. Both static and dynamic
testing can be performed, such as prefault and fault generation,
simultaneous ramping of several quantities and wave form editing.
FREJA 300 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 use of the GPS receiver accessory, GPS200 – MGTR, several
FERJA 300 can be synchronized to perform end-to-end testing
with the test sets allocated in different substations.
A FREJA 300 can be upgraded to a FREJA 306.
