Mechanical, electronic, algorithmic, and computer network facets are combined to create a highly integrated advanced gas sensor system. The sensor system, utilized with gas insulated high voltage switchgear products, deployed by electric utility end users in replacement and expansion cycles, function to detect and mitigate atmospheric pollution caused by leaking SF6. As its associated gas insulated tank is charged with 10 to 350 lbs. of SF6, each gas sensor monitors its local cache of gas, accurately sensing and computing fractional percentage losses (emissions) and gains (maintenance replacement) in SF6 mass, storing data in onboard data logs, and communicating data when triggered by detection events or in response to remote requests over a hierarchical communications network, a process that continues without labor until a fractional leak is automatically detected and reported creating the opportunity for early leak mitigation.

A pump for the transporting of fluids and / or of mixtures of fluids includes a housing (1) and at least one restrictor gap seal which is provided in the housing (1) to reduce the pressure in a restrictor gap along a rotatable part (2) of the pump, wherein the restrictor gap seal is formed as a brush seal arrangement (8). The brush seal arrangement (8) contains one or more individual brush seals (8′) which include as sealing members a plurality of sealingly arranged fibers, bristles and / or wires (8a) which are distributed and fastened in ring form and whose free ends extend towards the surface to be sealed.

The invention relates to an automatically quenching surge arrester arrangement with a surge arrester, which, on exceeding a given first voltage, transforms from a non-conducting into a conducting state and returns to the non-conducting state only when a much smaller second voltage is dropped below and with a switch mechanism reacting to current flow through the surge arrester, interrupting the current flow through the surge arrester and then automatically returning to the rest condition thereof. A simple, robust and compact assembly suitable for HF applications for such a surge arrester arrangement is achieved, whereby the switch mechanism reacts reversibly to the heat generated in the surge arrester by the current flow.
