the tests. 32 00:00:33,679 --> 00:00:40,605 In “Supply Direction” section, you can specify the injection and fault direction at the two sides of the protective device. 33 00:00:40,630 --> 00:00:50,091 By opening “Medium Detail View” window, you can see that on which side the fault point is located and by changing the “Supply Direction” type you can view that changes. 34 00:00:50,116 --> 00:00:55,685 Also, in this section it is possible to view the current amount, fault supplement direction etc. 35 00:00:55,710 --> 00:01:03,256 in “Fault Inception” section, the angle where the fault occurs is specified and the currents of the both sides are equally shifted. 36 00:01:03,281 --> 00:01:10,916 To better understand this, select “Signal View” from the toolbar and check “Voltage group A” from “Setting” and by changing the value of “Angle”, 37 00:01:10,941 --> 00:01:13,619 view the voltage and current signal changes. 38 00:01:13,644 --> 00:01:19,640 In differential test, if for any reason you wish to activate your voltages, you can use “Voltage Output”. 39 00:01:19,664 --> 00:01:24,398 In “Time” section, first, the injection time before the fault is entered in “PreFault Time”. 40 00:01:24,422 --> 00:01:31,727 In “Max Fault Time” the maximum fault injection time is specified in two forms of “Abs” or “Rel” which consist of three parts themselves. 41 00:01:31,751 --> 00:01:39,427 asfor this time note that if in a “Shot” point the “Max Fault Time” is shorter than “Pick up” time, the result of the evaluation will be wrong. 42 00:01:39,451 --> 00:01:48,578 If you are using the “Max Fault Time(Abs)” field, you need to enter a time in terms of seconds for the maximum fault signal injection time (for all of the points) but to accelerate the test, 43 00:01:48,602 --> 00:01:51,232 you can use the “Max Fault Time(Abs)” option. 44 00:01:51,256 --> 00:01:54,053 By checking this option, three other options appear. 45 00:01:54,077 --> 00:02:04,416 By entering a number in “Add %of Tnom”, the fault signal injection time in any point, equals the test point nominal time plus a percentage of the nominal time entered in this field. 46 00:02:04,440 --> 00:02:16,687 This means that if the test point nominal time is 10 seconds and 5 percent is entered in this field, the maximum fault injection time is 105 percent of the test nominal time which is 10.5 seconds. 47 00:02:16,711 --> 00:02:24,174 But in “Add Absolute” field, the fault injection time equals the sum of the nominal time of the test point trip plus the time entered in this field. 48 00:02:24,198 --> 00:02:28,074 If all these three fields are filled, the software picks the longest time entered. 49 00:02:28,098 --> 00:02:34,373 For points that are located at the “No Trip” zone, it is possible to enter a separate time in “No-Trip Time” field. 50 00:02:34,397 --> 00:02:37,736 In “Post Fault Time”, the injection time after the fault is entered 51 00:02:37,760 --> 00:02:40,866 “Delay after Trigger”, is used to enter the key trigger time. 52 00:02:40,890 --> 00:02:49,023 By right-clicking on the related field and selecting “Go to Linked Value”, you can see that it is linked to “CB Trip Time” and if necessary, 53 00:02:49,047 --> 00:02:53,513 you can replace it with your desired value by selecting “Remove Link”. 54 00:02:53,537 --> 00:02:59,202 “Time Reference”, by selecting “Fault Inception”, the “Trip” time is calculated from when the fault is injected. 55 00:02:59,226 --> 00:03:04,682 But by selecting “Starting”, the “Trip” is calculated from when the “Pick-up” contact is received from the relay. 56 00:03:04,707 --> 00:03:09,967 In “Load Current (PreFault Current)” you can specify the settings for the phase and current related to “PreFault”. 57 00:03:09,991 --> 00:03:18,091 In “Amplitude” section, by selecting “Based on Current” radio button, the “PreFault” current is entered in terms of Ampere which is the same for all test points. 58 00:03:18,115 --> 00:03:25,642 But by selecting “Based on IFault”, the “PreFault” current is entered according to the fault current which is different for every “Shot” point. 59 00:03:25,666 --> 00:03:29,646 In “Search Setting” section, the settings related to “Search Test” are specified. 60 00:03:29,670 --> 00:03:36,336 As mentioned before, a “Search Test” arrives at a conclusion only if one of the three conditions of this section is met. 61 00:03:36,360 --> 00:03:44,068 The first condition is “Relative” which means that if the difference between the test point value and the previous point is less than the percentage specified 62 00:03:44,092 --> 00:03:46,607 this very point is the result of the test. 63 00:03:46,631 --> 00:03:56,080 The second condition is “Absolute” which means that if the difference between the test point and the previous point is less than the value specified in this field, this very point is the result of the test. 64 00:03:56,104 --> 00:04:06,939 The third condition is “Max point number” which means that the test is to be performed as many times as the number of points entered in this field at max and the last point is the result of the test. 65 00:04:06,963 --> 00:04:12,980 But if for any reason, the nominal characteristic determined for the relay is not available, you can use “Ignore Nominal 66 00:04:13,004 --> 00:04:16,315 By doing so, the software ignores the existing characteristic. 67 00:04:16,339 --> 00:04:20,782 Then, based on the step entered in “Search Interval”, it adds shots on the “Search” line. 68 00:04:20,807 --> 00:04:23,958 For example, a line is drawn in “Search Test” section. 69 00:04:23,982 --> 00:04:28,963 Then, 0.5 is entered as the value for “Search Interval” and “Apply to All” is selected. 70 00:04:28,987 --> 00:04:33,325 You can see that some points with the same step are added on the “Search” line. 71 00:04:33,350 --> 00:04:41,334 By running teh test, you can see that the test starts from the lowest point and once one of the three mentioned conditions is met, the test arrives at a result. 72 00:04:41,358 --> 00:04:45,125 Also, if necessary, you can ignore this option by selecting “Disable all”. 73 00:04:45,149 --> 00:04:49,042 By selecting “Shot Passed Only Act In Main Zone” in “Other Setting” section, 74 00:04:49,066 --> 00:04:55,587 the test is passed only if the relay performance time in the shot point is somewhere in the allowed range of the main zone. 75 00:04:55,611 --> 00:05:03,718 This means that if this option is checked and a shot is added in the tolerance zone of the bottom of the characteristic curve and the relay gives a trip, 76 00:05:03,742 --> 00:05:06,631 the test fails because after checking this option, 77 00:05:06,655 --> 00:05:11,571 the relay performance is accepted only if it is at the upper zone of the characteristic curve. 78 00:05:11,596 --> 00:05:22,084 “Search Passed Only Act in Zone” is for “Search Test” and by checking this option, the “Search Test” is passed only if the relay trip is in the “Tripping” zone of the nominal characteristic curve of the relay. 79 00:05:22,108 --> 00:05:25,865 . In “Passed Setting” section, by checking “Pass if Get Any Trip” option, 80 00:05:25,889 --> 00:05:31,567 regardless of the relay performance time, if the relay operates in the “Tripping” zone, the test passes. 81 00:05:31,591 --> 00:05:39,504 In “Trigger” tab you can specify the desired binary to receive the “Pick up” and “Trip” signals of the relay as well as stopping the current injection. 82 00:05:39,647 --> 00:05:46,664 The settings and explanation of this section are exactly the same as mentioned for “Trigger” room and “Sequencer”. 83 00:05:46,688 --> 00:05:52,648 In “Binary Output” tab, if it is necessary for the relay to view the conditions of the key, 84 00:05:52,672 --> 00:06:01,710 it is possible to take any needed voltage to the “Binary Input” through “Binary Output” of the device by voltages of “A”, “B” or “Aux Dc” groups.This tab has three modes "PreFault","Fault", "Post fault" and you can configure each section separately.
