FREJA Win 3.0 3.1 4.0

3.1 Release notesWhat's new in this version 3.1 (compared to 3.0) AUTO 300          This is a new instrument. With this you can create automatic test sequences without any programming.  Distance          RX-Point. This is a new page in the Distance instrument that speeds up the reach test very much.          Whirlwind. This is also a new page in the Distance instrument. Current          Binary output list can now be used in “Time test”.  General          Phase rotation, Now it is possible to select between “0, 240, 120” or “0, 120, 240”.         Ramp, different types of ramps are added         Jump between the different states using PgUp/PgDn on the keyboard.         Test all, a new function to run all stored settings from the log.         Add test function to prepare a test off-line.         Pass fail function in sequence         1 more decimal on 100V and above. Sync          Larger range for frequency settings.          Lead time test, generate more than 1 turn. Some relays require 1 turn to stabilise.  Transducer          Higher resolution on the measurement values.         U-ref can be used as power supply for AC transducers         Possible to set primary values with decimal point Control center          Possible to set phase names         Possible to select default frequency         Possible to select default phase rotations for General (0, 240, 120 or 0, 120, 240)         New browser Reference graph          Possible to import a current vs. time reference graph from a textfile (txt). 

FREJA Win 3.1 4.0

4.0 release notesWhat's new in this version 4.0 (compared to 3.1) Auto21          This is a new instrument. The AUTO21 instrument converts and run “old” FREJA DOS testplans in the FREJA Win environment.

Transient          This is a new instrument. The Transient instrument can generate files from a disturbance recorder.          This is a successor to FREJA SIM DOS. AUTO 300          “Add info” with external path Distance          RX-point now also measure trip time         Bug fix (tolerance lines, Ke and Kphi, Re/Rl and Xe/Xl, Imp Z correction factor) Control center          On line indicator Reference graph          New Inverse curves (ANSI C37.112 and IEEE US C37.112 - 1996).

FREJA Win 4.0 5.0 5.1

5.0 release notesWhat's new in this version 5.0 (compared to 4.0) Voltage          This is a new instrument. The Voltage instrument is designed to test voltage relays.         This instrument works with the FREJA Win standard SW-key. Frequency          This is a new instrument. The Frequency instrument is designed to test frequency relays.          This instrument works with the FREJA Win standard SW-key. Autoreclose          This is a new instrument. The Autoreclose instrument is designed to test the autoreclose function.          This instrument works with the FREJA Win standard SW-key  General          Possible to select “Multiple frequency”, this means you can generate different frequency on each generator in Sequence mode.         Time measurement in ccs (cycles) Distance          Graphical report in PSB, Power Swing Blocking  Report templates          All report templates will be set (font and character set) according to your system the first restart after install. 

FREJA Win 5.0 5.1

5.1 release notesOver-Current reference curvesWe have added over-current curves for 94 relays. (Same functionality exists in SVERKER Win 2.1.) Pass/Fail limits in the General Ramp moduleWith Pass/Fail limits added to the general module we are now able to use the General instrument in automatic test schemes.When ramping we can specify a minimum and a maximum value. After the test, FREJA WIN will report the result as Pass or Fail,referring to the set acceptance values. New RIO format importIn the Distance instrument you can now import RIO files made in the new RIO format (2.1). Voltage Ramping “backwards” is now possible. Under Voltage Relays are now supported by ramping down into pick up.  Distance It is now possible to use Reference Voltage (Uref). This is useful for testing Distance relays that utilize Sync Check

Reference graph editorMore decimal digits in the fields.
