This window consists of 7 tabs of “Shot Test”, “Check Test”, “Search Test”, 68 00:00:38,779 --> 00:00:41,714 ”, “Stability”, “Setting”, “Trigger” and “Binary Output”. 69 00:00:41,739 --> 00:00:49,078 In “Shot Test” tab, you can select fault type and the points for the test and after the test is performed, you can view the results of the evaluation. 70 00:00:49,103 --> 00:00:55,888 In this tab, in “Test Point” section “Idiff” and “I bias” currents and in “Fault Type” section the fault type are determined. 71 00:00:55,913 --> 00:01:02,762 After specifying the test current, the fault type should be selected from among the standard faults available in “Fault Type” section. 72 00:01:02,787 --> 00:01:12,243 These faults include different faults of phase-to-earth, two-phase and three-phase. Before specifying the current and the fault type, you should determine “Supply Direction” in “Setting” section. 73 00:01:12,268 --> 00:01:16,937 By clicking on “Add”, the selected test point is added to the table in this window. 74 00:01:16,962 --> 00:01:25,609 By selecting one of the rows and clicking on “Insert” option, the selected row is repeated in the table and by clicking on “Remove” option, the selected point is removed. 75 00:01:25,634 --> 00:01:32,835 Also, by selecting “Add to” option, it is possible to copy point or points selected for one of the “Fault Types” to another “Fault Type”. 76 00:01:32,860 --> 00:01:38,111 By clicking on “Remove All” option, all test points entered in the table will be removed. 77 00:01:38,135 --> 00:01:45,268 By clicking on “Sequence” option, “Sequence Test Points to” page opens where it is possible to specify test points with equal steps. 78 00:01:45,292 --> 00:01:52,289 In “Step” section and in “Step On” field, by selecting “Angle” it is possible to directly specify the angular steps in terms of angle. 79 00:01:52,313 --> 00:02:01,950 This means that the test points are specified in accordance with the origin point and in “Origin” section, they are determined in a way that the required angles are resulted in proportion with the horizon. 80 00:02:01,974 --> 00:02:11,838 For example, if the start and end angles are “45” and “90” degrees respectively with “5” degrees steps and origin point for Idiff and I bias equal 5 times In, 81 00:02:11,862 --> 00:02:16,770 by approving this settings you can see that some points are added on the “Differential Characteristic”. 82 00:02:16,794 --> 00:02:20,900 For example, the last point is selected; by doing the mentioned calculation, 83 00:02:20,924 --> 00:02:32,548 in the picture you can see that the resulted angle is “85” and not “90” degrees which is because the “Origin” point is considered as one of the points and the last point of this “Sequence” is removed. 84 00:02:32,572 --> 00:02:43,240 But by selecting “Direction”, an angle is specified in “Angle” field and in this angle from the “Origin” point, with the length entered in “Length” field and with the steps specified in “Step Size”, 85 00:02:43,264 --> 00:02:46,063 some points are shot on the characteristic curve. 86 00:02:46,087 --> 00:02:50,321 Note that the length and steps of the points are based on nominal current. 87 00:02:50,345 --> 00:02:59,386 For example, if the angle is “45” degrees and the length is “5” and the step is “0.5” times the nominal current and the origin point is “0” amp, 88 00:02:59,410 --> 00:03:07,134 by approving this settings you can see that some points are added to the characteristic curve at the angle of 45 degrees with the origin of “0”. 89 00:03:07,158 --> 00:03:15,069 If the performed test has “Failed” points, by selecting “Clear All Failed Tests” option, it is possible to clear all these points from the table of this section. 90 00:03:15,093 --> 00:03:25,906 In “Detail” section, the information related to “Trip” nominal time, the allowed operation time range, actual time and test point evaluation are entered in “t nom”, “t min” and “t max” fields, 91 00:03:25,930 --> 00:03:28,186 “t act” and “Stage” fields respectively. 92 00:03:28,210 --> 00:03:32,102 The test points are entered with detail in the table at the bottom of the page. 93 00:03:32,126 --> 00:03:42,182 The details include test evaluation, test current, nominal time, operation time, fault value in terms of percent and seconds and the minimum and maximum operation time. 94 00:03:42,248 --> 00:03:47,192 Also, if you wish to add a comment about any of the test points, you can use the “User Comment” cell. 95 00:03:47,216 --> 00:03:51,886 At the end of this page, it is possible to select test points table from different “Fault Types”. 96 00:03:51,910 --> 00:03:55,971 After performing the “Shot Test”, “Check Test” and “Search Test” are performed. 97 00:03:55,995 --> 00:04:04,130 In “Check Test” the upper and lower tolerances of the relay, which are displayed as dotted lines in “Differential Characteristic”, are tested and evaluated. 98 00:04:04,154 --> 00:04:10,635 To perform the “Check Test”, first it is necessary to draw some lines named “Check Line” in different parts of the vector. 99 00:04:10,659 --> 00:04:17,621 To draw this line, first from “Origin” section in “Check Line” section, the start point of this line is specified. 100 00:04:17,653 --> 00:04:30,583 In “Idiff”, “I bias”, and “Angle” fields, 2In, 3In and -30 degrees are entered as origin differential current, origin bias current and the angle of the check line respectively. 101 00:04:30,608 --> 00:04:37,019 Also, 1In is entered as the length of the check line in the cell of the “Length” section. 102 00:04:37,043 --> 00:04:43,504 Note that the drawn “Check Lines” must have at least one intersection with one of the characteristic curve tolerance lines. 103 00:04:43,528 --> 00:04:47,635 Then click on “Add” option to add the “Check Line” to the “Check Test” table. 104 00:04:47,659 --> 00:04:59,138 Another method for drawing the “Check Line” is to hold down left-click and “Ctrl” key on “Differential Characteristic” window and then move the cursor in the desired direction on the characteristic curve. 105 00:04:59,162 --> 00:05:04,295 You can see that the information of the drawn “Check Line” is displayed in “Check Test” lines table. 106 00:05:04,319 --> 00:05:13,511 After drawing the “Check Line”, the software evaluates the crossing place of “Check Line” and tolerance lines as “Shot” test in accordance with the performance of the relay. 107 00:05:13,535 --> 00:05:21,773 Here, after performing the test, the relay does not perform in lower tolerance and performs a trip in the upper tolerance so the result of the test is “Pass”. 108 00:05:21,798 --> 00:05:26,129 Other parts of this section such as “Fault Type” and “Remove All” and “Sequence” etc. 109 00:05:26,153 --> 00:05:32,189 options are the same at those of “Shot Test” section which have been explained in previous parts. 110 00:05:32,213 --> 00:05:35,391 The only additional option in this section is “Copy to Search”. 111 00:05:35,415 --> 00:05:38,515 By marking any of the test lines and selecting this option, 112 00:05:38,540 --> 00:05:46,144 it is possible to copy the selected line in “Search Test” and by selecting “Add” option in “Search Test”, add this line to the “Search Test” table.
