Filed: 2017-02-08
Abstract: Embodiments of the disclosure relate to systems (100) and methods for determining a fault location in a three-phase series-compensated power transmission line system by using symmetrical components-based formulas that describe various voltage and current relationships. The voltage and current relationships can be derived using a synchronous measurement procedure that is concurrently executed at a sending end and a receiving end of the first series-compensated power transmission line system (100). Furthermore, determining the fault location in accordance with certain embodiments of the disclosure can eliminate one or more of a need to calculate an impedance value of any of the series capacitors (105) or the series capacitor protection elements (115) that are a part of the three-phase series-compensated power transmission line system (100), a need to monitor any of the series capacitor protection elements (115), and a need to measure a voltage drop across any of the series capacitors (105).

Filed: 2021-02-22
Abstract: Innan ytskikt läggs på exempelvis ett golv, vill man försäkra sig om att den relativa fuktigheten i ytan eller närmast därunder är tillräckligt låg. Kända metoder för detta är dels fuktmätning i laboratorium på uttaget prov av betong eller avjämningsmassa, dels fältmätning med en fuktgivare i ett borrat hål i betong eller avjämningsmassa. Laboratoriemetoden är omständlig och borrhål grundare än omkring 20 mm kan med känd teknik inte användas. Enligt uppfinningen skruvas ett metallblock (3) fast i mätobjektet ovanpå ett borrhål (6). En fuktgivare (1) placeras i en brunn (4) inuti metallblocket (3). Fuktutbyte mellan givare (1) och mätobjekt sker via en öppning (7) i blocket (3) och ett mätrör (8) i borrhålet (6).Brunnens (4) längdaxel bildar högst 20 graders vinkel med mätobjektets yta. Därigenom kommer fuktgivaren (1) nära mätobjektet och skillnaden mellan deras temperaturer blir liten.

Moreover, the output shaft is mounted on bearings at the center of chamber block, whereby drive force losses occur. In the rotary engine according to the invention, the rotor (1) has a fixed shape and the movements of the engine rotor are arranged to occur alternatingly about two different support points (P2, P3), and that the rotor connecting rod mechanism which rotates the output shaft (4) during the power stroke is arranged to utilize a long lever principle of nonarticulated rigid connection rods by virtue of locating the pivotal support point (P2) of the engine output shaft, and thus the distal end of the lever arm extending from said support point, to both sides of the chamber block center point so as to make the distal end (B) of the lever arm which transmits the rotating force exerted by the rotor to be farther distanced from the rotor motion support point (P2) than from the chamber block center point.
