Abstract The measurement system on atmospheric electric field and its EMC problems
are introduced were analyzed. The compatibility and reliability could be enhanced by
means of improving PCB layout, grounding, providing high-frequency return path,
shielding, and mounting devices for ESD and lightning. Finally, the EMC and anti
-lightning performances of the system were proved to adapt the severe operating
environment of the system.
Keywords atmospheric electric field measurement; electromagnetic compatibility; PCB;
