Current testing device HDJB-8000

voltagecomputer-controlledprotection relay

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.
