Improvement of a proposed model for heat conduction in an electrode submitted to an electric discharge: Application to the indirect determination of the anodic and cathodic voltage drops

摘要

We present an improved version of a heat‐conduction model which leads to better‐computed values of the anodic voltage drops for electric discharges in a liquid dielectric, with a short interelectrode gap (about 50 μm) and short duration (10–1000 μs). The results obtained show monotonic variations according to the duration of the discharge and peak current, and correspond to the measured value of the total interelectrode voltage drop.
