Freja 300 relay testing system weighs only 15kg and features a rugged hardware design that is built for field use over a wide temperature range with the possibilities of intelligent software to perform rapid testing.
Freja 300 relay testing system can be operated with or without a PC. After being put into the Local mode, Freja 300 can be used as a standalone system 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 4x150 V (82 VA) and 3x15 A (87 VA) or 1x45 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 also be used as a disturbance simulator and create as well as generate simulated disturbances, or import actual recorded disturbances from EMTP or COMTRADE files by using the Freja SIM Disturbance Simulator Software.
With the built-in DC source, the user can supply the relay protection.
