to perform “Search Test”. 83 00:00:37,064 --> 00:00:40,327 The purpose of this test is to find the characteristic curve line. 84 00:00:40,352 --> 00:00:46,613 To perform a “Search Test”, first some lines named “Search Line” should be drawn in different parts of the vector. 85 00:00:46,638 --> 00:00:50,879 The method for drawing these lines is the same as the one explained for “Check Line”. 86 00:00:50,904 --> 00:00:56,861 To draw this line, first the start point of this line is specified in “Search Line” section, “Origin” section. 87 00:00:56,886 --> 00:01:08,633 In “Idiff”, “I bias” and “Angle” fields, the origin differential current 2In, the origin bias current 3In and search line angle -30 degrees are entered respectively. 88 00:01:08,665 --> 00:01:13,339 The length of the check line 3In is entered in the cell of “Length” section. 89 00:01:13,364 --> 00:01:17,529 Then, click on “Add” option to add the “Check Line” to “Check Test” table. 90 00:01:20,973 --> 00:01:31,994 Another method for drawing the “Search 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. 91 00:01:32,018 --> 00:01:37,144 You can see that the information of the drawn “Search Line” is displayed in “Search Test” table. 92 00:01:37,168 --> 00:01:45,992 After drawing the “Search Line”, the software evaluates the crossing place of “Search Line” and tolerance lines as “Shot” test in accordance with the performance of the relay. 93 00:01:46,016 --> 00:01:54,731 By performing the test, the software interpolates the characteristic curve by testing some points on the search line to find the exact location of the characteristic curve. 94 00:01:54,755 --> 00:02:00,957 “Ignore” field in “Search Interval” section is used when you wish to ignore the characteristic curve specified for the “Search” line. 95 00:02:00,981 --> 00:02:07,189 By entering a number in this section, some points are added on the “Search” line with the entered number as their distance. 96 00:02:07,214 --> 00:02:16,174 For example, by entering 0.4 in this field, you can see that there are points added on the “Search Line” with as much as 0.4 of distance. 97 00:02:16,198 --> 00:02:24,136 If the test is performed, the points added on the “Search Test” are tested one after the other so that the exact location of the relay is specified. 98 00:02:24,161 --> 00:02:30,337 This option is used when there is no characteristic curve for the test or the current characteristics seem to be wrong. 99 00:02:30,361 --> 00:02:37,854 If you want to do this for all drawn test lines, you can use the “Setting” tab in “Ignore Nominal Characteristic” section. 100 00:02:37,878 --> 00:02:47,613 To do so, by entering the value of “Search Interval” and selecting “Apply to all” option, you can apply this settings to all test lines and find the relay characteristic. 101 00:02:47,637 --> 00:02:47,714 S 102

00:02:49,132 Stability tab: 116 00:02:49,156 --> 00:02:57,512 “Stability” test is performed in this tab. In “Stability” test, for zero “I diff”, for every “I bias” the relay must not perform a trip. 117 00:02:57,536 --> 00:03:06,721 If you hold down the “Ctrl” key and click on the characteristic curve, you can see that the shot points are located at the bottom of the characteristic curve and on the zero differential current line. 118 00:03:06,745 --> 00:03:13,316 In fact, in “Shot Test” you can select different bias currents by zero differential current and perform a stability test. 119 00:03:13,340 --> 00:03:20,380 The other explanations for this page are the same as those for “Shot Test” tab and you can watch the video related to that section.
