Description

technical field [0001] The invention relates to the field of lightning monitoring and early warning, in particular to a multi-channel comprehensive lightning monitoring instrument. Background technique [0002] my country is a country with frequent lightning disasters. With the development of electronization and informatization, a large number of electronic equipment such as communications, computers, and switches are widely used in people's lives. These electronic equipment have low withstand voltage and are easily damaged by lightning current. With the improvement of people's requirements for surge protection, it is a basic work to do a good job in lightning protection by analyzing the characteristics and laws of surge voltage generated by lightning strikes on the line, and record the specific conditions of surge voltage generated on the line when lightning strikes occur It is the foundation. At present, the lightning recording devices on the market can only record the a...
