In order to study the relationship between the amplitude (mV) and the discharge (pC) of a typical fault of a tip discharge in a partial discharge. Therefore, three different groups of tip electrode models (tip-tip, tip-plate, tip-ball) were simulated. The relationship between magnitude and discharge volume and voltage was obtained by using amplitude detection method (Ultra High Frequency Method, Acoustic Emission Method and Transient Earth Voltage method) and Pulse Current Method respectively. Kendall correlation analysis found that the amplitude and the voltage of the AE Method in the three amplitude detection methods are closest to the variation trend of the discharge quantity and the voltage of the Pulse Current Method. Exploring the equivalence between the amplitude and the discharge of the most accurate detection means, the mathematical model with the best fit is the Sum of Sin Functions.
