General Information
HDJB-8000 Relay Protection Tester is an important test equipment which can test devices of various professional fields(such as microcomputer protection,relay protection,fault recorder and excitation measurement)all by itself.
Main Features:
1. Six phase voltage and six phase current output. It can test not only traditional relays
and protection devices, but also modern micro-computer protectiondevices, especially for
transformer differential protection andstandby automatic switching device. The test is
more convenient and perfect.
2. Friendly man-machine interface, easy and fast operation; high performance embedded
industrial control computer and 8.4 inchresolution 800 × 600TFT truecolor display
screen, can provide rich and intuitive information, including the current working state of
the equipment and various help information.
3. This Windows XP system has its own recovery function to avoid system crash caused
by illegal shutdown or misoperation.
4. Equipped with ultra-thin industrial keyboard and photoelectric mouse, it can complete
all kinds of operations through keyboard or mouse justlike ordinary PC.
5. The main control board adopts DSP + FPGA structure and 16 bit DAC output. It can
generate 2000 high density sine wave per week for fundamental wave, which greatly
improves thequality ofwaveform and the accuracy of the tester.
6. The high fidelity linear power amplifier ensures the accuracy of small current and the
stability of large current.
7. USB interface is used to communicate with PCdirectly without any connecting line, so
it is convenient touse.
8. can be connected to laptop (optional) to run.Laptops and industrial computers use the
same set of software, so there is no need to relearn the operation method.
9. It has the function of GPS synchronization test.The device can be built-in GPS
synchronous card (optional) and connected with PC through RS232 port to realize
synchronous test of two testers in different places.
10. Equipped with independent dedicated DC auxiliaryvoltage source output, the output
voltage is 110V (1a), 220V (0.6A).It canbe used for relays or protection devices that
need DC power supply.
11. It has the function of software self calibration, which avoids openingthe case to
