Abstract: An electrical circuit for connecting an electrical measurement device (16), which is used to measure partial discharges in a power grid having an operating voltage in the range of 1-69 kV, and which has an A/D converter (17) for converting a measured voltage pulse into a digital signal and has a microprocessor unit (18) for evaluating the digital signal, with a measurement output of a capacitive voltage testing system (3) of switchgear for the power grid having the operating voltage in the range of 1-69 kV. The electrical circuit (8) has a frequency response matching resistor (9) which is connected between an input line (10) for connection to the live pole of the measurement output and to ground, and has a high-pass filter (11) connected down-circuit of the frequency response matching resistor (9).

Abstract: A method for accurately locating a cable defect of an in-ground cable for transmitting electricity, in which a precise position is established with a mobile pinpointing device based on an approximate position of the cable defect that was established previously. A distance of the defect location of the cable from a current position of the mobile pinpointing device is determined by the mobile pinpointing device. The current position is captured by the mobile pinpointing device using a GPS receiver. Subsequently, at least one possible precise position is determined by the pinpointing device based on the captured current position of the pinpointing device, the established distance of the defect location from the current position of the pinpointing device and the extent of the cable that is stored in the pinpointing device.

Abstract: A steering column for a motor vehicle is adjustable at least in its longitudinal direction. The steering column includes a support unit chassis of the motor vehicle, a setting unit and a clamping mechanism which comprises a clamp bolt and at least one arrest element cooperating with at least one securement element. At least one arrest element during the closing of the clamping mechanism is displaced in the axial direction of the clamp bolt with respect to the support unit and clamped with a securement element connected with the setting unit, and at least one securement element is connected with the setting unit so that in normal operation it is held nondisplaceably in the longitudinal direction of the steering column with respect to the setting unit and in the event of a crash is displaceable with respect to the setting unit under energy absorption. The support unit includes on both sides of the setting unit side jaws, through which penetrates the clamp bolt through openings.
