"Overcurrent" Characteristic Curve

2
00:00:21,508 --> 00:00:27,777
Continuing the explanation of the "Overcurrent" room, this video introduces the "Overcurrent Characteristic"window,

3
00:00:28,254 --> 00:00:34,523
where the characteristic curve is displayed.In the "Overcurrent Characteristic", the current-time inverse curve is shown.

4
00:00:35,000 --> 00:00:42,222
In this window, you can use a series of shortcut keys to add points to the table and perform the test more quickly.

5
00:00:51,587 --> 00:00:59,682
To add test points to the "Test View" table, you can click on the characteristic curve and press the "Add" button to add points to the test table.

6
00:01:00,079 --> 00:01:08,095
Additionally, by holding down the "Ctrl" key and clicking on the curve, you can add the desired points to the test table more quickly

7
00:01:09,524 --> 00:01:14,523
The third method for adding points to the test table is by entering the

8
00:01:14,683 --> 00:01:20,000
 "I test" current in the "Test Point" section and pressing the "Add" button

9
00:01:20,397 --> 00:01:23,730
as explained in the previous tutorial videos.

10
00:01:24,524 --> 00:01:29,682
After adding test points to the table, click "Start/Continue Test"

11
00:01:30,000 --> 00:01:35,396
from the toolbar at the top of the screen or press the F5key.

12
00:01:36,349 --> 00:01:42,698
This will start testing all the points in the "Test View" table sequentially.

13
00:01:44,048 --> 00:01:49,523
If you want to test each point individually, this can be done in two ways:

14
00:01:49,921 --> 00:01:58,253
1. Click on "Start Single Test" from the toolbar at the top of the screen or press the F9 key.

15
00:01:58,730 --> 00:02:02,698
2. Right-click on the desired row and select "Apply & Start Test".

16
00:02:03,016 --> 00:02:08,015
Additionally, if you want to test a point without adding it to the table,

17
00:02:08,244 --> 00:02:14,116
click on the desired point in the characteristic curve and then click "Start Single Test".

18
00:02:18,323 --> 00:02:26,021
In the top toolbar, you can change the time curve display using the "Time in Seconds" and "Time in Cycles" options.

19
00:02:35,387 --> 00:02:43,640
Additionally, by changing "Relative Values" to "Absolute Values", you can view the current values in amperes.

20
00:02:43,800 --> 00:02:47,212
Switching between "Primary Values" and "Secondary Values"

21
00:02:47,609 --> 00:02:52,847
also changes the values based on the primary and secondary nominal values.

22
00:02:53,005 --> 00:02:58,560
Note that these changes are applied not only in the "Characteristic View" window

23
00:02:59,038 --> 00:03:04,275
but also in other sections of this room, such as the "Test View" window

24
00:03:05,307 --> 00:03:10,783
In the "Overcurrent Characteristic" window, by clicking on the gear icon at the bottom,

25
00:03:11,260 --> 00:03:18,878
you can apply additional settings for better analysis. Each of these settings will be explained in the following sections.

26
00:03:19,355 --> 00:03:27,132
The "Zoom during Test" option is used to zoom in on test points on the characteristic curve while the test is running.

27
00:03:28,005 --> 00:03:35,147
The "Optimize All" option is used for optimal display of the characteristic curve for all "Fault types".

28
00:03:35,784 --> 00:03:40,148
The "Pan Mode" option allows for moving the characteristic curve,

29
00:03:40,466 --> 00:03:45,783
 which can also be done by holding the "Alt + Mouse Click" keys.

30
00:03:46,339 --> 00:03:53,640
The "Horizontal Axis" option is used to display the horizontal axis of the characteristic curve relative to the data.

31
00:03:54,593 --> 00:04:00,783
The "Show Row Number" option displays the row number of the information entered on the curve.

32
00:04:01,815 --> 00:04:07,132
The "Show All Tact Point" option displays the operating time

33
00:04:07,530 --> 00:04:10,624
of all test points on the characteristic curve.

34
00:04:11,260 --> 00:04:17,688
If the selected test points are close to each other, you can use the "Show Selected Tact Point" option

35
00:04:18,006 --> 00:04:21,815
for a better display of the operating time for each row.

36
00:04:22,768 --> 00:04:30,783
Note that if both "Show All Tact Point" and "Show Selected Tact Point" are selected at the same time,

37
00:04:31,022 --> 00:04:36,736
the operating time of all test points will be displayed on the characteristic curve.

38
00:04:41,895 --> 00:04:48,720
If you want to add a test point exactly on the current lines, you should use the "Snap To Grid" option.

39
00:05:07,688 --> 00:05:11,418
The "Show Cursor Value" option is used to

40
00:05:11,657 --> 00:05:16,974
display the current value and nominal time of the test points on the characteristic curve

41
00:05:17,688 --> 00:05:24,513
If you also want to have the details of each "Curve", you can check the "Show Curve Information" option.

42
00:05:25,625 --> 00:05:31,418
The "Out of range" option indicates the area where the device cannot inject.

43
00:05:31,973 --> 00:05:42,845
For example, since the current limit is set to 32A in this case, any area beyond this current is shown as out of range.

44
00:05:43,561 --> 00:05:50,783
Additionally, there are options available in the right-click menu of this window, which will be explained further below.

45
00:05:51,577 --> 00:05:57,529
the "Shot" section, by using the "Add shot" option, the point where you right-click will be added

46
00:05:58,006 --> 00:06:06,021
to the test table. Using the "Single Shot at" option, the test will be performed for the selected point (as "Start Single").

47
00:06:10,863 --> 00:06:19,593
the "Zoom" section, the options "Zoom Mode," "All," "In," and "Out" are explained in the videos in the "Sequencer" section.

48
00:06:20,403 --> 00:06:31,037
The "Characteristic" and "Test Points" options set the display to show the characteristic curve and the range where the points have been "Shot," respectively.

49
00:06:44,212 --> 00:06:50,482
In the "Show" section, the options "Tolerances," "Tests," and "Shots" in the "Curve,"

50
00:06:50,641 --> 00:07:00,164
"Tests," and "Grid" areas, respectively, are used to toggle the display or hide the tolerances of the characteristic curve,

51
00:07:00,482 --> 00:07:06,593
test points, and horizontal and vertical lines in the "Characteristic View" window.

52
00:07:21,831 --> 00:07:27,069
In the “Color” section, you can change the background color using the “Backgroundoption,

53
00:07:27,863 --> 00:07:33,894
 the grid line color with “Grid”, and the tolerance area color with “Tolerances”.

54
00:07:34,371 --> 00:07:39,609
 You can also use “Color Default” to reset these colors to their default settings.

55
00:07:40,403 --> 00:07:47,148
The options under the “Other” section are the same settings accessible through the gear icon

56
00:07:47,625 --> 00:07:53,497
at the bottom of the screen, which were explained at the beginning of this video

57
00:07:54,133 --> 00:08:00,402
Using the "Export as image" option, you can export the current view of the "Characteristic View" window

58
00:08:00,641 --> 00:08:05,243
as an image in formats like jpeg, png, and others.

59
00:08:05,482 --> 00:08:11,990
Also, in the left toolbar of this window, the tools are listed from top to bottom as follows:

60
00:08:12,387 --> 00:08:21,990
"Cursor," "Undo," "Redo," "Zoom mode," "Optimize All," "Zoom In," "Zoom Out," "Pan mode," and "Show cursor value."
