Secondary winding potential distribution of Tesla transformer

A non-uniform parameter double-transmission-line model is created to explore the voltage distribution in Tesla-transformer taper windings. With the method of differential approximation, the numerical results are shown that during the charging process of PFL, the maximal electric-field intensity moves gradually from the small-radius end to the large-radius end, whereas during the discharging process and the abnormal discharging process of PFL, the maximal electric-field intensity is on the large-radius end. What’s more, the maximal electrical field intensity of the three processes, which happens in the abnormal discharging process of PFL, is approximately 1.5 times the average electric-field intensity.
