Product Description

Megger FREJA 300 Protective Relay Testing & Simulation System

  • You are bidding on an Megger FREJA 300 Protective Relay Testing & Simulation System. It will arrive with a fresh calibration with test data performed by Megger. It will also include all the Multi Cable, Test Lead Sets, Softcase and other accessories . The FREJA 300 relay testing system is a computer-aided relay testing and simulation system. The weight of FREJA 300 is only 33 lbs. The rugged hardware design is built for field use over a wide temperature range, with the possibilities of intelligent software to perform rapid testing. 
  • 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 (87VA) 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 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 FREJA 300 can be synchronized to perform end-to-end testing with the test sets allocated in different substations.
