A current pause device configured to enhance the operation of transmission
and distribution line circuit interrupters by delaying the voltage build
across the circuit interrupter arc gap for a time period sufficient to
allow the dielectric characteristic of the medium within the arc to
recover. This allows the circuit interrupter to break the circuit at a
lower arc gap voltage than would occur without the current pause device.
The current pause device includes a conductive arcing horn and an
insulator interposed in the arcing horn to create a conductive gap in the
arcing horn and a voltage protection arrangement to limit the voltage
across the current pause device and thereby prevent a voltage breakdown
across the current pause device. Specifically, the voltage protection
arrangement includes a diode connected to the arcing horn in parallel
with the insulator and a dielectric spark gap device connected in
parallel across the insulator.
