As you can see 5 “States” are created. 54 00:01:32,145 --> 00:01:43,855 In the first “State” 30 volts is applied, the “Actual” is measured and calibration factor is obtained from the difference between these two so that the test voltage is more accurate during the test. 55 00:01:43,880 --> 00:01:49,649 Note that while applying this voltage, the switches are open and no voltage is applied to the “CT”. 56 00:01:49,674 --> 00:01:52,781 The second “State” is related to “At Calibration State”. 57 00:01:52,805 --> 00:02:04,590 The fourth “State” is the specified test voltage and the third and fifth “States” are half and double the test voltage respectively which are created to measure the best state of the primary voltage. 58 00:02:04,614 --> 00:02:09,404 Note that this is why the maximum voltage limit is 220 volts. 59 00:02:09,428 --> 00:02:14,412 In “Voltage Measurement Mode”, the “Input” specified to measure the voltage. 60 00:02:14,436 --> 00:02:21,609 Note that this item changes automatically according to the test voltage and the turns ratio specified in “Test Object”. 61 00:02:21,633 --> 00:02:27,058 After entering the “State Setting” information, you need to do the wiring according to the picture. 62 00:02:27,082 --> 00:02:30,737 Note that by double-clicking on it you can maximize it. 63 00:02:30,761 --> 00:02:34,838 In this wiring, “Va1” must be connected to “S1” 64 00:02:34,862 --> 00:02:37,483 while “N” must be connected to “S2” 65 00:02:37,507 --> 00:02:43,537 and then a wire must be connected to “Input10” for measurement after passing through the “CT”. 66 00:02:43,561 --> 00:02:55,775 After doing the wiring, 50 volts and 1 second are entered as test voltage and test time for “CT Protection 500/1” and after pressing “Init Test”, the test starts. 67 00:02:58,314 --> 00:03:04,921 In “Signal View”, the waveform of the voltage along with its “Actual” value and the measured voltage can be viewed. 68 00:03:04,945 --> 00:03:09,288 After the test is finished, the results can be viewed in “Turns Ratio Result”. 69 00:03:09,312 --> 00:03:19,430 “Vactual”, “Vmeas” and “Turns Ratio Nom” are the actual value of the fed voltage, the measured voltage and the “CT” nominal turns ratio respectively. 70 00:03:19,454 --> 00:03:32,385 Also, “Turns Ratio Act” is measured by comparing “Vmeas” and “Vacutal” and finally, the assessment is recorded in assessment field in accordance with the difference between “Turns Ratio Act” and “Turns Ratio Nom”. 71 00:03:32,409 --> 00:03:38,495 If the difference is less than the allowed value in the standard, the test passes otherwise it fails. 72 00:03:38,519 --> 00:03:44,793 Here, since the error percentage is less than the specified value in the standard, the test is passed. 73 00:03:44,817 --> 00:03:51,894 This test is assessed in the way that when you specify a test voltage, the current is measured according to the “Burden” 74 00:03:51,918 --> 00:04:01,434 entered in “Test Object” and after performing the test and measuring the turns ratio error percentage, the result is compared with the current standards table and assessed. 75 00:04:01,458 --> 00:04:07,586 In “Phase Nom” field in “Phase” section, the phase and in “Phase Act”, the measured phase are specified. 76 00:04:07,610 --> 00:04:17,501 In “Phase Dev” by comparing “Phase act” and “Phase nom”, the error is calculated in minute and the assessment is specified in “Assessment” field. 77 00:04:17,525 --> 00:04:22,667 “Pol.Check” field in “Polarity” section checks the correctness of the polarity. 78 00:04:22,691 --> 00:04:30,635 Finally, after the test is performed, it is necessary to add the assessment to the report which is done by pressing “Add to Report”. 79 00:04:30,659 --> 00:04:38,645 Also, if you wish to add some specified parts to the report or delete the report you can use “Add to Report” cog. 80 00:04:38,669 --> 00:04:44,949 Note that if the test has been performed using inputs and outputs other than the default settings, 81 00:04:44,973 --> 00:04:52,998 first you need to click on “Init Test” and then check “Don’t Change Hardware Setting” and by going to “Hardware Configuration”, 82 00:04:53,022 --> 00:05:01,880 in “Analog Output”, activate phases of the intended voltage group and deactivate the rest and perform the test using the intended voltage group. 83 00:05:01,904 --> 00:05:12,585 Here voltage group A is deactivated and voltage group B is activated and instead of “Input 10”, “Input 8” is selected and the necessary settings is adjusted. 84 00:05:12,609 --> 00:05:15,437 No test is performed in “Megger” tab. 85 00:05:15,778 --> 00:05:23,047 This section is designed so that you can enter “Megger” test result and gather all results in one report. 86 00:05:24,436 --> 00:05:31,835 You can enter the number of rows and columns that you need in “Rows” and “Column” fields respectively and by clicking on “Insert”, 87 00:05:31,859 --> 00:05:37,021 make your intended table and the results are added to the inserted fields. 88 00:05:38,045 --> 00:05:42,665 Also, in “Title” field you can enter a title for your test. 89 00:05:42,689 --> 00:05:51,516 Finally, after all the tests are performed and the results are added to the report, in “Report View” it is possible to view the report as a whole. 90 00:05:51,540 --> 00:05:58,615 By right-clicking and selecting “Reorder Reports”, it is possible to change the arrangement of different test results. 91 00:05:58,639 --> 00:06:07,270 To do this, you need to select your intended report and by using “Up” and “Down” keys move the report or by using “Delete”, delete it. 92 00:06:07,294 --> 00:06:16,639 Furthermore, if you wish to delete the added report, or edit the entered information, you can use the blue option named “Edit & Delete Report”.
