On the basis of the experiment model of metal protrusion, the relationship between UHF measurement and pulse current method was investigated by theory and experiment results. The results indicate that the optimal regression curve is energy of UHF signal relative to square of apparent discharge quantity. The variation of voltage has no impact on the regression curve. However, while the distance between protrusion and plate is changed, the slope of regression curve changes according to it and the same energy is corresponding to bigger discharge quantity.

Bazując na eksperymentalnym modelu rozrzutu metalu w powietrzu badano zależność pomiaru UHV i metodą prądu pulsującego. Stwierdzono, że energia sygnału UHV zależy w kwadracie od natężenia wyładowania. Wprawdzie energia wyładowania nie zależy od zmian napięcia ale wraz ze zmianą odległości między elektrodami wyładowania zmienia się kształt krzywej regresji w zależności od napięcia.
