Abstract: In order to detect the current state of a system component, e.g. to display whether an electrical conductor, a cable or the like, is currently live, a field generator that generates a magnetic field in the environment of the system part is provided, which generator is connected to an organic magnetoresistive OMR semiconductor element that is arranged stationary in the environment of the system component to be monitored, and a voltage source for generating an electrical voltage between two electrodes of the OMR semiconductor element is provided. The device and the method can be fitted in a simple manner and cost-effectively to almost any system part, even at a later stage to already existing systems. A corresponding display shows the desired information locally limited and in the simplest manner: if the electric conductor is currently energized, an additional evaluation is not necessary.

Abstract: A method for early detection of developing damage in a bearing caused by flow of a bearing current includes evaluating a long-term measurement of a measured variable representative of a bearing current amplitude of a bearing current during a bearing operation, representing—based on the evaluation—measurement results in form of a histogram which displays a number of bearing currents per time interval in each interval of the bearing current amplitude, and evaluating the histogram representation of the measurement results through pattern comparison. A device for carrying out the method is also disclosed.

Abstract: A method for evaluating component-related energy models and external specification parameters, in order, based on these, to produce a determination of a set of partial-load conditions, which are simulated based on a parameterizable simulation model of the system. A system planner is put in a position, with the specification of specification parameters, for example, a minimum throughput of the system or a maximum energy consumption, in which he can obtain a set of partial-load conditions, i.e., a partial-load condition for each of the components involved in the determination. In this way, an individual partial-load condition can be set for each component, where all the partial-load conditions fulfill the provisions of the specification parameters.

Abstract: In a method for planning a power distribution network for an installation having a multiplicity of power consumers, time-dependent load profiles for the power consumers are created as a function of a change, over time, in inertial masses to be speeded up, slowed down and/or kept in motion using the power consumers, and time-dependent power profiles are created for the power consumers. A network plan is created for the power distribution network, and a time-dependent power profile is computed for the installation. Network components of the power distribution network are dimensioned as a function of the computed time-dependent power demands on the network components.

Abstract: A force transducer, in particular a load cell, includes a spring body that deforms when loaded with a force or load to be measured. Two support parts, which are separated by a gap, are moved out of a position of rest. A capacitive displacement detector is used to detect the relative movement of the support parts, where the capacitor includes two electrode combs that are each held on one of the support parts and includes a multiplicity of electrode fingers. The electrode combs are configured designed and mounted on the two support parts such that the electrode fingers of the one electrode comb pass into the finger interspaces of the other electrode comb when the spring body is loaded so that the force transducer is resistant to overloading.

Thus, the degree of dirt and/or dew of said voltage intermediate circuit converter can be determined at least during a charging process of an intermediate circuit capacitor of a voltage intermediate circuit converter, thereby preventing a breakdown including the consequences thereof.
