An electric power distribution switching device including a detector for detecting accidental arcs in the electric power distribution switching device, which detector includes at least one waveguide in which the light generated by the arc and reaching it via its casing is used as a triggering or warning criterion. The detector can include a support rod, a waveguide wound helically around the support rod, and two plug connectors fitted at the ends of the support rod. The detector also includes a heat-shrink sleeve which is permeable to light and UV radiation. The heat-shrink sleeve is fitted over the support rod, the waveguide and the plug connectors. A detector configured in this manner can prevent damage to the detector during installation or fitting in the switching equipment.

Optical fiber accidental arc detector for an electric power distribution

Substation for the distribution of electrical energy, and protected against arcing faults, characterized by the fact that Hall-effect sensors and additional optical fiber conductors are provided as sensors, whereby the Hall-effect sensors are logically AND linked with the optical fiber conductors.

Substation for the distribution of electrical energy protected against

An apparatus for electrical connection which has good contact characteristics, consists of simple parts, is easy to assemble and install, and is also suitable for the electrical connection to C-shaped bus bars or bus bars with slot shaped tap zones, which bus bars are preferably in withdrawable unit distribution boards or panels. The apparatus preferably has a mounting element, elastic contact elements, and a plug element. The plug element preferably has a plug shell, a contact strip, and contact laminar strips, which contact laminar strips are embedded in window like openings of the plug shell and act as elastic current bridges between the bus bar or socket element and the contact strip carrying the current located within the connection apparatus.
