FREJA546R

Relay Test System

www.megger.com 1

DESCRIPTION

The FREJA546R is a multi-purpose, lightweight, field portable test set

capable of testing a wide variety of electro-mechanical, solid-state,

and microprocessor-based protective relays, motor overload relays,

and similar protective devices. The FREJA546R has the “smart”

combination of being both small and light weight, while also providing

high power. The FREJA546R has a new case design, with improved

distributed power supplies for additional reliability as well is a larger

on-board display and additional memory.

The FREJA546R test system can be manually controlled with the

integrated onboard display on the FREJA546R running the new RTMS,

Relay Test Management Software. The 25.7 cm onboard display, with

its large, easy-to-read full colour, high resolution, TFT LCD touch screen

allows the user to perform manual, steady-state, and dynamic testing

quickly and easily using the manual test screen, as well as using built-

in pre-set test routines for most popular relays. The onboard display

eliminates the need for a computer when testing virtually all types of

relays. Menu screens and touch screen function buttons are provided

to select the desired test function quickly and easily. Tests results can

be saved to the internal memory for later download to a USB Thumb

drive to transfer or print test reports. For fully automatic testing every

FREJA unit is supplied with Relay Test Management Software (RTMS)

for installing on a PC. It does not require a security dongle or license

to operate and can be loaded on as many customer-owned computers

as required. There are two different levels of RTMS: Standard and

Enhanced, see ordering information for details.

APPLICATIONS

The test system may be customised by adding the number of voltage/

current, “VIGEN”, modules needed for specific test applications,

with a maximum of three channels. For example, the FREJA546R

with three VIGEN modules provides complete three-phase testing

of three-phase impedance, directional power, negative sequence

overcurrent, and other devices that require a three-phase four-wire

wye connected sources. The fourth voltage channel provides an AC

reference/ synchronising/polarising voltage, or a DC battery simulator

voltage source. Each current channel is rated for 32 A at 200 VA RMS

continuous, and up to 60 A at 319 VA RMS for short durations. For

testing relay panels or electromechanical relays, it has a unique flat

power curve from 4 to 32 A that always ensures maximum compliance

voltage to the load. With a maximum compliance voltage of 50 V

RMS per phase, two channels in series provide 100 V to test high

impedance relays. Three currents in parallel provide test currents up

to 120 A at 600 VA for testing ground overcurrent relays at high

multiples of tap rating. With three currents in parallel it can provide

up to 180 A at 957 VA for testing all instantaneous overcurrent relays.

Each voltage channel can provide variable outputs of 0–30/150/300

V at 150 VA of output power. Automatic range changing is done

on-the-fly and under load. For testing a panel of relays or older

electromechanical impedance relays, it has a unique flat power curve

from 30 to 150 V always insuring maximum output power to the

load. With the VIGEN voltage channels converted to currents, a three

channel unit can provide six currents for testing three phase current

differential relays, including harmonic restraint transformer differential

relays.
