HZJB-I Portable Three Phase Relay Protection Tester

This device has 10 channels digital input and 8 channels output.

The switching input circuit is compatible for both the empty contacts and 0-250V electric potential contacts in the input and output circuit. When the electric potential contacts are selected, 0-6V belongs to closed switch and 11-250V belongs to open switch. The switching capacity can test the action time and the action time interval of every phase switch's contact conveniently.

The part of the digital input is isolated from the resources of the mainframe and the amplifier. The end of the digital input is hung, so the common end of the digital input is separated from the Common End UN, IN of current and voltage parts.

Switching potential input has directivity, you should connect the common end with the positive terminal of potential, and connecting the input end with negative terminal of potential for ensuring the potential of common end is higher than the one of input end. In practice, you should connect the input common end with ＋KM, and connecting the negative terminal of contact with input end.

The output part is the idle contact output of relay. Output capacity is DC：220V／0.2A,AC：220V／0.5A. Output of switching capacity is independent of voltage, current, input and all other parts. Action process of each digital output part is different in each testing module. For details, please refer to the operation instruction on software module.

Fault Review

fault Review is used for putting the data documents of current-voltage waveforms compiled in Data Format ANSI/IEEE C37.111-1991COMTRADE that is recorded by data recording equipment like fault waveform recorder in the tester, and its waveforms will be reviewed by tester for testing equipment like protection tester.

Each standard recording document consists of three kinds of documents. They are respectively pilot, configuration and data document. Names of these three kinds of documents are the same, which can be differed by different suffix names that are respectively .HDR, .CFG and .DAT. The review test can't be done unless three documents are complete.

Before the test, please open certain recording document at first. Recording document can be laid in any subentry that can be found in the dialog box of 'open the document'. The program will list all documents whose suffix name is .CFG after finding the subentry. After selecting certain document, the program will transfer automatically the .CFG and .DAT documents of this name, and display all voltage-current waveforms and name of channel on the screen. In addition, you can also check document's attribute, waveform discretion sampling point, etc. through the buttons in tool column.

Press the 'Test' key to enter a dialog of several pages testing options:

Page 1： Select wave recording voltage and current line needs to be tested. You can select in the mode of whole group of voltage, whole circuit of current, and also can select separately and independently three-phase voltage or three-phase current.

Page 2： Selecting the wave recording segment of time, starting-end points, needs to be reappeared. Basic unit of time point is according to numbers of waveform sampling point. You can input data on time point, and also can increase or reduce it by pressing the '↑' key and '↓' key on keyboard.

Page 3： Outputting it in original ratio or outputting it after the change of PT and CT in transformation ratio. When outputting in transformation ratio, you should divide the data by this transformation ratio value. In addition, if data of certain phase needs to output after 180ْ revrse phase, you can set the transformation ratio to be a negative number such as '-1/1', then this phase will be output in original anti-phase ratio.

Page 4： Transmitting automatically all selected data to the lower machine for waiting for reappearance output.

Page 5： Doing the reappearance test officially. The 'upper button' on this page makes the tester to output circularly the first periodical waveform, and waiting for your pressing of 'lower button'; press the 'lower button', the tester will output all recording waveforms till the end point of reappearance time segment for reappearing whole process. You can also don't press 'up key' but press directly 'down key', it will reappear completely all waveforms from starting time segment to end time segment in one time.

After ending the test, computer will file the testing result in the subentry of 'test report\fault reappearance' in text format, and it can be displayed or printed by pressing the 'print' key. You can also copy it to be compiled or amended by compiling tools like WORD.
