[0002] Plasma discharge modules play an important role in industrial and technical fields. It is a device that can generate thermal plasma under complete local thermodynamic equilibrium conditions. This plasma is considered as a conductive fluid mixture and can be modeled by magnetohydrodynamic equations. Under equilibrium discharge conditions, the model mainly focuses on gas temperature and electric field, sometimes also considering the velocity and pressure of the background gas, without delving into the chemical composition of the plasma.

[0003] The ground electrode of the plasma discharge module is one of its key components and is crucial for ensuring the effective operation of the entire system. The ground electrode is usually made of conductor materials such as copper, aluminum or copper-plated materials, and its design aims to introduce current into the ground to reduce the potential rise of power equipment and lines, thereby improving the reliability and safety of the power system. The ground electrode is connected to the underground electrode and plays a role in guiding the grounding current, while the plasma pole is the part of the ground electrode that contacts the air and is responsible for maintaining the formation of the plasma layer and the conduction of current. The plasma ground electrode generates plasma by exciting oxygen molecules in the air, forms an arc, and then forms a plasma layer with high conductivity around the ground electrode, effectively fixing the grounding resistance. This grounding electrode system is not only widely used in power systems, telecommunications systems, petrochemical systems and other fields, but also has the advantages of reducing grounding resistance, saving space, and strong corrosion resistance.
