    摘要: The invention relates to a method for determining the loop resistance of a power supply network with a neutral conductor (called N), a phase or external conductor (called L1), a ground or protective earth conductor (called PE), and a fault current breaker (called FI) based on the differential quotient Ri=dU/dI≈(U1−U2)/(I1−I2); whereby U1 is the measured, unloaded network voltage, I1 is the zero current without load, U2 is the measured, loaded network voltage, and I2 is the calculated load current. According to one aspect of the invention, the following steps are provided: Loading of a L1-N loop and determining the resistance RL1 according to equation (1), loading of a N-PE loop with a measuring current IM under a measuring voltage UM which is small enough to avoid triggering of the fault current circuit breaker, and determining the resistance RPE according to the following equation (2): RPE=UM/IM  (2) and determining the loop resistance as RL1+RPE.

    摘要: A structural element has at least one slide layer and is formed to slide via the at least one slide layer along at least one line of motion. The slide layer includes a fiber-reinforced material containing at least one multi-component fiber that includes at least one first component, which is disposed in or on at least one first structure, and at least one second component, which is disposed in or on at least one second structure. The first and second structures are materially-bonded together and are disposed parallel to each other in a main extension direction of the at least one multi-component fiber. Either the first component or the second component is polytetrafluoroethylene. The structural element may be formed, e.g., as a bearing ring, a slide bearing bushing, a linear guide or a spherical bearing ring.
