PSB (Power Swing Blocking)
General, GPS sync
General Graphical results
Distance, RIO interface
Distance Zt, Automatic reference graph
Distance Zt, Border test
Current, Log-log scale
3.1 Release notes What'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).
4.0 release notes What'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 C and IEEE US C ).
5.0 release notes What'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.
5.1 release notes Over-Current reference curves We have added over-current curves for 94 relays. (Same functionality exists in SVERKER Win 2.1.) Pass/Fail limits in the General Ramp module With 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 import In 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 editor More decimal digits in the fields. Windows XP installation and French language General relations
