The weight of FREJA300 is only 15 kg. The rugged hardware design is built forfield use over a wide temperature range, with thepossibilities of intelligent software to perform rapid 300 can be operated with or without a PC. Afterbeing put into the Local mode, FREJA 300 can be usedstand-alone without a PC. Using the Local mode is of each key is described on the display,which also presents the settings and measured values.

2 The very accurate (typically ) low level analogueinputs are designed for transducer measurements. Thehigh level inputs can be used as a normal volt- andammeter. FREJA 300 can generate 4x150 V (82 VA) and3x15 A (87 VA) or 1x45 A (250 VA) and the FREJA 306 cangenerate 6x15 A (3x15 A + 3x35 A) or 1x100 A (750 VA).Each output can be varied independently. Both static anddynamic testing can be performed, such as prefault andfault generation, simultaneous ramping of severalquantities and wave form 300 can also be used as a disturbance simulator andcreate and generate simulated disturbances, or importactual recorded disturbances from EMTP orCOMTRADE files (and edit the wave forms), by using theFREJA SIM Disturbance Simulator Software.

All settings are saved automatically when youexit, but if you prefer you can assign the settings a nameand save them separately for convenient access when youconduct your next test. The display can also show themeasured value that is being generated. This feature isequivalent to three voltmeters and three ammeters thatpresent RMS values for all generators. On the Sequence page, you can vary all generatorparameters independently. You can have up to 25 differentstates (prefault, fault1, fault2, fault3 etc.). This is usefulwhen testing autoreclose relays or motor protection.

5 On the Ramp page, you can ramp all generator parametersindependently. Amplitudes and angles are shown on avector diagram, and values can be set with a dial,keyboard or mouse. It s also possible to generate up to the25th Distance instrument program is designed to testdistance relays. On the Configuration page, you enter thenumber of zones that are to be tested and also the timeand impedance tolerances, thereby creating an automatictest. No programming is needed. Later, when you recallthis object via the Control center, all settings are re-established so that you can start testing immediately. On the Connect page you enter information about how tomake connections to the Relay , including pictures if sodesired.

7 Normally, you test one type of fault at a time whentesting relays. With FREJA Win, however, you can test allseven fault types automatically if so desired. All you haveto do is press the <Start> button. FREJA will test all sevenfault types automatically and then compare the readingswith the theoretical values that you entered on theConfiguration page. If the readings are OK, a green lamplights. If not, a red lamp lights. If you want to check thereverse direction, the test can start below zero ohms in the3rd RX-ramp page, which is part of the Distanceinstrument program, is designed to test the reach of adistance Relay . First, you define the start and stop anglesand the delta phi between the ramps.

8 Then press the<Start> button and relax. FREJA will automatically test allseven types of faults using the timesaving search-half method. You can also define your own ramps, using themouse to specify starting and ending points whereverdesired. If you have defined a theoretical reference graph,the program will compare the actual test result with yourgraph and check for any deviations from the tolerancesentered on the Configuration page. If the results are OK, agreen lamp lights. If not, a red lamp , RX RampDistance, RXThe RX page enables you to define test points can define different points on the oscilloscope usingthe mouse or keyboard. Select the automatic mode andpress the <Start> button.

9 FREJA will test all points for theselected fault types. The points will be assigned differentcolors, depending on the trip time. If you select themanual mode, you can use the dial to search for RX point page, a new feature in FREJA Win ,speeds up the reach tests . Reference graphsEfficient testing and performance analysis require well-defined reference values. FREJA can automatically createthe IEC and IEEE standard curves for overcurrent relays. Itis also possible to create reference graphs in theimpedance plane using the included library of distancerelays made by major manufacturers and/or create othercharacteristics using the standard circular lens and linearelements (including mho, quadrilateral and ice-cream coneshapes).

The optional ProGraphfeature enables you to import the parameter settings froma master selectivity plan prepared in Microsoft Excel.
