Three phase relay tester triphase microcomputer relay protection tester device 3-phase relay test set
1.Meet all test requirements on site.The instrument hasstandard four phase voltage and three-phase current output. It can test notonly various traditional relays and protection devices, but also
various modernmicrocomputer protections, especially for transformer differential protectionand standby automatic switching device. The test is more convenient andperfect.
2.All kinds of technical indexes fully meet the standard of DL /t624-1997 "technical conditions for microcomputer based test device ofrelay protection" issued by the
Ministry of electric power.
3.Classic Windows XP operation interface, friendly man-machineinterface, easy and fast operation; high performance embedded industrialcontrol computer and 8.4 inch resolution 800 × 600 TFT true color display screen, can provide rich and intuitiveinformation,
including the current working state of the equipment and varioushelp information.
4.This Windows XP system has its own recovery function to avoid systemcrash caused by illegal
shutdown or misoperation.
5.Equipped with ultrathin industrial keyboard and photoelectric mouse,it can complete all kinds of
operations through keyboard or mouse just likeordinary PC.
6.The main control board adopts DSP + FPGA structure and 16 bit DACoutput. It can generate 2000
high density sine wave per week for fundamentalwave, which greatly improves the quality of
waveform and the accuracy of thetester.
7.The high fidelity linear power amplifier ensures the accuracy of smallcurrent and the stability of large
current.
8.USB interface is used to communicate with PC directly without anyconnecting line, so it is
convenient to use.
9. can be connected to laptop (optional) to run.Laptops and industrialcomputers use the same set of
software, so there is no need to relearn theoperation method.
10.Equipped with independent dedicated DC auxiliary voltage sourceoutput, the output voltage is
110V (1a), 220V (0.6A).It can be used for relaysor protection devices that need DC power supply.
11.It has the function of software self calibration, which avoidsopening the case to calibrate the
accuracy by adjusting the potentiometer, thusgreatly improving the stability of accuracy.
