Abstract: This method of checking at least one operating parameter of an energizer supplying an electric fence with high-voltage shock pulses consists, on the one hand, in producing a measurement signal having a value representing the operating parameter to be checked and controlling the production of the shock pulses as a function of the measurement signal in such a way that a time interval between the shock pulses is a function of the value of the measurement signal, and, on the other hand, in performing the following steps in any zone along the electric fence, remotely from the energizer: picking up the shock pulses; evaluating the time interval between the picked up pulses; and operating an indicator so as to provide an indication about the operating parameters, as a function of the evaluated time interval.

Abstract: Several storage condensers (1, 1′, . . . 1″) are mounted in parallel. Several thyristors (2, 2′, . . . 2″) are each mounted in parallel with one condenser (1, 1′, . . . 1″) to ensure the individual discharge of each condenser without modification of the condition of the other condensers. The discharge of the condensers (1, 1′, . . . 1″) is controlled in sequence so as to deliver to the secondary of the transformer a complex pulse comprised by a series of elemental pulses, each elemental pulse corresponding to the individual discharge of one condenser.
