Thus the discharge, when it occurs, is staggered, coming initially from the first capacitor and then from both.

The invention relates to an electrode holder comprising an electrode cooling device on its underside, said cooling device being electrically insulated from the electrode holder in order to prevent damage by arcing.

When the discharge spark gap between the two electrodes (1, 2) is ignited, an electric arc (4) is generated in a discharge chamber (5) that connects the two electrodes (1, 2).

As a result the combustion effect is improved obviously.

Means and measures are disclosed which largely eliminate the harmful effects of high-voltage flashovers.

The thermal element may be configured to trip in a safe manner without sparking or creating exposed energized conductors.

electric field produced by these charges, which in turn results in a force or a disruptive discharge.

A series arrangement of a capacitor (20) and a first breakdown switch (13) is connected between said two input terminals (1 la; l l b).

A series arrangement of a second breakdown switch (14) and a primary winding (31) of a transformer (30) is connected in parallel to said capacitor (20).

Disclosed are a measurement device and a puncture device that prevent thermal loss and enable decreased cost in laser units.

The transistor is intermittently triggered into its breakdown or avalanche mode, and an antenna (56) is coupled to the inductor (L1) for transmitting the energy pulses.

Phase controlled rectifier loads and arcing devices produce continuous noise unless adequately filtered.

The noise of this disruptive discharge has imitated that of two small pieces of artillery fired at an invaluable interval, yet distinct from the ear.
