摘要： A transducer arrangement for a nondestructive ultrasonic material testing system has a multiplicity of ultrasound transducers which can be moved linearly or swiveled along a trajectory curve. A multiplicity of ultrasound transducers can be aligned with a point of a specimen. If the size and the focal length of the transducers prohibit an annular or similar arrangement, the transducers are divided into smaller groups. They are then arranged so that every transducer passes over each desired focal point on the specimen during movement of the transducers along the trajectory curve.

摘要： Calibration for an ultrasonic nondestructive materials testing system is specified, the system having an array of ultrasonic transducers which can be linearly moved and pivoted. In order to compensate for the offset between the beam direction of the ultrasonic transducers and the rotation point of the pivoting system or another desired point of the transducers, this offset is determined using a calibrating body which is, for example, spherical.

摘要： Calibration for a nondestructive ultrasonic material testing system is provided, the system having a multiplicity of ultrasound transducers which are linearly movable as a whole but are arranged fixed with respect to one another, for example mounted fixed in a single sensor holder. In order to achieve optimal alignment of the sensors with a specimen, the mechanical tolerance-induced offset between the beam direction of the ultrasound transducers and the ideal beam directions is found, for example with the aid of a mean straight line. It is then minimized by using the available degrees of freedom of the sensor holder, for example possible tilting of the sensor holder.

摘要： In a device and method for non-destructive materials testing with at least one ultrasonic transducer, the transducer is able to be moved by a movement system in at least one direction to a workpiece surface. The emission of ultrasonic by the ultrasonic transducer is able to be synchronized with the activation of the movement system so that electrical interference caused by the movement system occurs at times at which no echo is expected for ultrasonic emitted by the transducer. The method and device can be applied to non-destructive materials testing with ultrasound.

摘要： An electric measuring device is supplied with electric energy at a high-voltage potential by a circuit that includes at least one first transformer on the ground potential side. The first transformer has a primary side, to which a generator is attached to generate a feed signal that supplies energy, and a symmetrically sub-divided secondary side with a division point connected to the ground potential. The circuit also has at least one second transformer on the high-voltage potential side with a symmetrically sub-divided primary side, whose division point is connected to the high-voltage potential and a secondary side, to which the measuring device can be connected for the energy supply. In addition, at least one symmetrically configured transmission element attenuates the potential and is equipped with two parallel sub-branches running between the secondary side of the first transformer and the primary side of the second transformer. To divide the voltage, each respective transmission element includes at least two voltage dividers, each having an intermediate nodal point. The respective transmission element can be connected to the measuring device via both nodal points by a respective line to measure the voltage.

摘要： A method of manufacturing a wound insulator pipe, in particular for a high voltage insulator, having one or more ducts for conductors of any kind is provided. A laminate structure is achieved by winding a material onto a spindle and impregnating with a resin. Initially first layers of the material to be wound are applied; then at least one groove is made in the surface obtained and then the winding is completed until the final diameter is attained.
