    摘要: Procedure and device for adaptive and continuous detection of voltage drop in the electrical wiring system of buildings and of national/local electrical networks that continuously detects, in an adaptive way, the voltage drop and warns the user about this failure and/or disconnects the faulty circuit. It contains a new method of current voltage drop detection by using an adaptive reference that follows the variation of steady-state voltage instead of fixed upper and lower safe limits, used by current methods. The steady-state voltage is continuously recorded and used as reference. This reference is compared to the voltage at outlet output after the electrical device has been plugged in and during its usage. If the difference of voltage is outside of the range of values established by the norms for voltage drop, a warning is generated and/or the faulty circuit is disconnected.

    摘要: Voltage instability protection for an electric power system is implemented by determining a change in power injected into a region of interest within the electric power system based on synchronized power measurements from different power injection points of the region of interest (200), and by determining a change in power absorbed by one or more loads in the region of interest based on synchronized power measurements from different load points of the region of interest (210). A change in power loss for the region of interest is determined based on the difference between the change in power injected into the region of interest and the change in power absorbed by the region of interest (220). A voltage instability condition is indicated when the change in power loss for the region of interest approximates the change in power injected into the region of interest (230).

To this end, the method comprises the following steps: (a) eliminating negative input signal half-waves, (b) stepping down the residual positive input signal half-waves, (c) testing whether the value of the stepped down input signal half-waves is above or below the threshold value (L) and generating a first binary signal (S1) according to the testing, (d) monitoring, said monitoring being carried out simultaneously to steps (a) to (c), of the zero crossings of a reference signal formed by alternating voltage and generating a second binary signal (S2) according to the monitoring, (e) generating a third signal (S3) by delaying the second signal (S2) at a defined delay time (TV) such that a state change of the third signal (S3) results at the time of the respective vertex of the positive input signal half-waves, and (f) deciding whether the value of the positive input signal half-waves is above or below the threshold value (L), whereby a fourth binary signal (S4) is generated by evaluating the first signal (S1) at the time of the state change of the third signal (S3).

    摘要: A device for providing electric power from a signal transmitter (2) with at least two signal outputs for a load (3) which requires the application of voltage of both polarities as simultaneously as possible. Here, the signal outputs (Sl to Sn) to be used for power supplies are allocated via rectifier components, especially diodes (12) to a first output (6) of a first polarity and a second output (7) of a second polarity. They are switched via a switching component (8) which is controlled by the signal outputs (Sl to Sn) concerned. In addition, the load (3) is connected via a series-mounted voltage converter (9).
