It is well known that microcomputer harmonic elimination can effectively eliminate the over-voltage generated by resonance in the system, so as to maintain the safety of the system. It is suitable for unattended substation or integrated automation equipment. Another point is that the microcomputer harmonic elimination device automatically records the fault information in the background.

The microcomputer harmonic elimination device can automatically record the fault information in the background, and record the data in the electronic chip through the background electronic automatic recorder, and display and read the data through the liquid crystal display screen. The LCD screen can recall the recent 20 grounding fault information. On site staff can directly check the data information on the microcomputer harmonic elimination device. And the data can be transferred to the computer, and further data can be saved and analyzed in the later stage. The historical data can be copied out through the USB data port on the device by using U disk. In addition, the information of microcomputer harmonic elimination device will not be lost after power failure, which is also a major feature of fault information recording of microcomputer harmonic elimination device.

The microcomputer harmonic elimination device has the dual functions of storage and recording. Compared with the traditional data information recording, it is particularly important for users to use the device more confidently.
