Circuit safety needs the protection of microcomputer harmonic elimination device. Because of its high technical content, safety and reliability, the device was once sought after by people. Microcomputer harmonic elimination device uses microcomputer technology for power grid harmonic elimination, and uses computer's fast and accurate data processing ability to realize fast Fourier analysis, and its frequency selection is accurate. By collecting the voltage of the voltage transformer, the various frequency components of the power grid resonance can be quickly analyzed, and the grounding fault, voltage transformer disconnection and resonance fault can be accurately identified.

In the process of transportation and storage, the equipment of microcomputer harmonic elimination device should be placed upright to prevent the equipment from tilting and colliding. At the same time, please pay attention to clean and dry environment to prevent gas and liquid corrosion.

Before using the microcomputer harmonic elimination device, it is necessary to check whether the equipment in the device is in good condition and whether the wiring port falls off. All switches should be in the off position and the voltage regulator should turn all the way counterclockwise.
