heal.abstract	Common industrial insulators (phenol impregnated press-board, bakelite) were subjected to various voltage pulses with maximum applied fields up to 1 MV/cm. There is experimental evidence that when the applied pulse exceeds a threshold electric field (0.2 MV/cm for the examined materials), the potential profile across the dielectric develops discrete potential steps. This might be brought by instant high conductance due to the presence of high mobility electrons. This is in agreement with the arguments for S-type negative differential resistance effects under high field application in organic dielectrics. An evaluation of the energy of electrons which are collected at the anode electrode is attempted.	en
