Abstract (en)
[origin: WO9510784A1] Method and device for determining the flashover characteristics of an insulator (5) using an electronic microscope (1) in which the electron flow in the beam (3) is adjusted on the basis of electrons lost, particularly backscattered, secondary or absorbed electrons. A control device (9) responding to certain sensors (10, 12) is provided for the purpose. The electron flow rate is proportional to the voltage simulated in the insulator.
