2. When you finish your work proceed to disconnect the test leads from the Mentor 12 first then from the test objects In this way you will prevent any voltage from accidentally touching the surrounding objects or yourself You can then turn the unit off directly No software shutdown procedure is required Initial check We recommend you to carry out a general check on your particular unit in order to confirm that it has been configured properly according to your specifications This will take you less than 5 minutes NOTE The procedures below assume that the Mentor 12 is in its initial power on state e no changes have been made to the default factory settings e OUTPUT AMPLIFIERS CONFIGURATION The initial factory defined layout shows three voltage sources at the upper half and three current sources at the lower half of the Basic Control screen Their default presets are 63 5 V for the voltage sources 1 A for the current sources and 0 240 120 for the angles Power sources are represented by colored red yellow blue rectangles labelled Vs for voltage and Cs for current However this basic layout does not represent the maximum output capabilities of your Mentor 12 By means of the Configuration menu you can add the following to the standard power layout a any combination of up to SIX current mode or voltage mode LOW LEVEL SOURCES regardless to the number of power channels that you have ordered or b any c

As you can see on the screen it is possible to enter data to define ratios that affect groups with three sources three phase system as it is assumed that the protection transformers are identical for each phase at one same measurement point IMPORTANT You must enter the data corresponding to voltage in the following way In the window corresponding to Primary Rated Voltage you must enter the rated value of the transformer primary in Phase Volts to Neutral e g 127020 V and in the window corresponding to Secondary Rated Voltage you must enter the rated value of the transformer secondary in Phase Voltages to Neutral e g 63 510 V SECTION 4 CONFIGURATION Page 100 Note IMPORTANT You must enter the data corresponding to Current in the following The voltage transformers are usually defined by their primary and secondary voltages between phases not from Phase to Neutral The values entered in the previous example correspond to a transformer that you will normally find defined as 220 KV 110 V You must divide both the primary and secondary values by the square root of 3 to find the values of Phase Voltage to Neutral You can enter different values for the sources Vs from 1 to 3 and for sources Vs from 1 to 6 way In the window corresponding to Primary Rated Intensity you must enter the rated value of the transformer primary in Amps e g 2000 A and in the window corresponding to Seco
