Description

Overview

The Megger FREJA549 is a versatile, lightweight and portable relay test system for secondary testing of protection relays. Providing up to nine current channels, it can be operated standalone from its built-in touchscreen running FREJA Local, or fully controlled from a PC through FREJA Win software — a powerful yet portable solution for protection engineers.

Key features of the Megger FREJA549 relay test system

Up to 9 current channels for transformer and bus differential relay testing
High current capability for all types of overcurrent relays (electromechanical, solid-state and numerical)
High compliance voltage for testing high-impedance earth fault relays
Handles voltage-controlled, voltage-restraint and directional overcurrent relays
Standalone touchscreen operation (FREJA Local) or full automation via FREJA Win
Second-generation Megger automatic / semi-automatic interface

FREJA549 relay testing applications

The FREJA549 is used to commission and maintenance-test differential, overcurrent, earth-fault and directional protection relays and schemes in substations and industrial installations. Its nine current channels make it particularly suited to transformer and busbar differential schemes, while high compliance voltage supports high-impedance earth-fault protection.
