Description

technical field [0001] The invention belongs to the technical field of inductive conductivity measurement using a voltammetric characteristic method, and in particular relates to a multipurpose electrode for inductive conductivity measurement. Background technique [0002] Insulation medium has now become a key component of modern electrical and electronic devices, and conductivity has always been one of its most basic and important parameters. The radiation-induced conductivity caused by various high-energy particle radiation under complex space environment conditions is the key to measure the performance of the medium in the spacecraft. Studies have shown that the induced electrical conductivity caused by high-energy radiation in space directly reflects the accumulation of electrostatic charge inside the polymer, the ability to release electrostatic charge and the change state of the insulating properties of the material. When the induced conductivity continues to increas...
