Description

The Megger Freja 300 is an advanced three-phase protection relay test set from the Megger Programma Freja series, used for comprehensive testing of modern numerical protection relays. It generates precise three-phase currents and voltages with independent phase and frequency control for testing distance, differential, directional, and other complex relay schemes. The Freja 300 supports automated test sequences via PC software and is a standard tool in transmission substation commissioning.
