摘要： A method for determining the wear on a contact element of an electrical switch, for example, of a switching installation for high or medium voltage, includes recording electrical values which represent an electrical variable, which is relevant to an arc occurring at the switch during a switching operation, as a function of time, and calculating a wear value, which represents the wear on the contact element, from a plurality of wear contribution values. The wear contribution values are calculated from a plurality of subsets of the recorded electrical values using a plurality of wear contribution calculation rules, with the result that each of the wear contribution values is calculated from a respective one of the subsets of values according to a respective one of the wear contribution calculation rules. At least two of the wear contribution calculation rules differ from one another.

摘要： The disclosure relates to a method for operation of a flow measurement device, and to a flow measurement device itself. In order in this case to record the conductivity of the medium or faults resulting from deposits by means of a measurement tube configuration in a technically simple manner, a total of at least 4 electrodes are arranged distributed on the circumference of the measurement tube, in the measurement tube. When a signal is fed in at one of the electrodes or at an electrode pair, an electric current is measured between one electrode pair, while an electrical voltage is measured between another electrode pair. An impedance value is determined from the two measured values, from which impedance value a conductivity of the medium is determined and/or in comparison of different conductivities or in comparison with historical values, it is deduced that there is a covering layer on the electrodes.

摘要： A method is disclosed for operating a flowmeter, such as an inductive flowmeter, in which a medium flows through a measuring tube, and an arrangement of electrodes are conductively connected to the medium. To determine a filling level in a simple and reliable manner, at least four electrodes are arranged in the measuring tube essentially in a half-circumferential region based on a cross section through the measuring tube. When at least one signal is fed in at one of the electrodes or at one of the electrode pairs, an electrical current is measured at an electrode or between an electrode pair. An electrical voltage is measured between at least one other electrode pair or with respect to a common connection to ground. When comparing measurements with two different electrode combinations, different voltage and current values are related to infer a diagnosis, such as a filling level in the tube, and/or an electrode coating, and/or an oblique installation, and/or a sedimentation at a bottom of the tube. The diagnosis can be used to correct a flow rate.
