' In a previous work (Models of High-Voltage Qenerators Operating is m
Liquid Dieleatrio) deacribin teats on niodele or ale I
6 otroetatic high voltage
machines, xa investigated the operating principle oT eleotrostatio maohiAes ~
developed by ua and analysed their worlcibg oyole; namely: l) oharging at
primary potentials 2) rising of potential out-oft
~ 3) of` oharge at high
potential, and l~) loxering o~ potentihl oP the remaining oharge to the
primary potential. The dependenoe of aeoondary potential on oharge ourrent
