In this diagram the "X" axis is the current axis, and the "Y" axis is the time axis. 54 00:01:11,382 --> 00:01:13,439 In “Axes” section, to show the curve, 55 00:01:13,463 --> 00:01:20,607 the current range is specified in terms of “IPu” and the time range is specified in terms of seconds. 56 00:01:20,631 --> 00:01:29,939 For example, here the current range is specified between 1 “IPu” and 100 “IPu” and the current axis is displayed between 1 and 100 “IPu”. 57 00:01:29,963 --> 00:01:41,272 “IPu” is the “CT” secondary nominal current. Also, by unchecking the “Logarithmic” option, it is possible to change the diagram display from logarithmic to regular. 58 00:01:41,296 --> 00:01:52,511 Also, by using “Open” and “Save” options it is possible to save the created file in this section and open it again on this page and edit or use it if necessary. 59 00:01:52,535 --> 00:01:57,938 Now, from the toolbar click on “New” to open a new blank page for the new curve. 60 00:01:57,962 --> 00:01:59,319 In “Point” section, 61 00:01:59,343 --> 00:02:14,146 enter the current in “Current” field and time in “Time” field and then “Add” them to the points table of the intended characteristic curve so that it is displayed in the diagram at the right side. 62 00:02:14,170 --> 00:02:19,991 or by using the “Ctrl” key and clicking on the diagram, it is possible to create the characteristic curve. 63 00:02:20,023 --> 00:02:30,102 By using “Add” and “Insert” buttons, it is possible to add the point entered in “Point” section to the last row of the table and before the selected row respectively. 64 00:02:30,126 --> 00:02:34,321 If the user has a logarithmic image of the relay characteristic curve, 65 00:02:34,345 --> 00:02:43,855 it is possible to “Load” it in this window by using “Load Image” option and create the relay characteristic curve for the test by adding the point on the entered curve. 66 00:02:43,879 --> 00:02:49,819 Now, here we enter an image of the “7UT63” relay overcurrent characteristic. 67 00:02:49,843 --> 00:02:56,198 Then it is necessary to equalize the “Scales” of the diagram in this page with the “Scales” of the entered diagram. 68 00:02:56,222 --> 00:03:07,170 To do so, first, by using Alt+left click combination key the current and time axes of the entered image are equalized with the current and time axes of the “Grabber” window. 69 00:03:07,194 --> 00:03:15,813 Then, the “Start” and “End” values are specified in “Current” section as 1.05Pu1 and 1.45 respectively. 70 00:03:15,861 --> 00:03:26,637 Also, the “Start” and “End” values are specified in “Time” section as 0.05 and 200 seconds. You can see that both diagrams are completely overlapping. 71 00:03:26,661 --> 00:03:37,571 Note that these numbers are different for images with different sizes and they need to be specified by the user in a way that the two diagrams overlap in terms of values and size. 72 00:03:37,595 --> 00:03:47,189 Now, by holding down the “Ctrl” key and clicking on the curve with “Dial Setting=0.1”, this characteristic curve is created and approved. 73 00:03:55,839 --> 00:03:59,942 If you wish to save this curve in the software for future tests, 74 00:03:59,966 --> 00:04:06,814 , by selecting “Save”, the intended characteristic curve is saved in this folder and is usable for next tests. 75 00:04:06,853 --> 00:04:17,161 Note that if a later version of the software is installed, this saved file is removed from the “User Defined” folder. So before installing the new version of the software, 76 00:04:17,185 --> 00:04:28,027 it is necessary to make an output “Xml” file by using the “Export” button from “Manage Select Characteristic” page and then “Import” it to the new version. 77 00:04:28,051 --> 00:04:34,966 This characteristic curve is displayed in the diagram on the right side of the “Overcurrent Protection Parameters” window. 78 00:04:34,990 --> 00:04:38,811 Note that for the characteristic curves created using this method, 79 00:04:38,835 --> 00:04:56,656 the time entered in “Time” column of the characteristic table of the characteristic curve is a coefficient which is multiplied by the times entered in the characteristic points table and as a result it influences the characteristic curve time and relay operation time.
