摘要： A system detects physical variables of at least one component of a tapped transformer and monitors the at least one component of the tapped transformer. The system includes a computer in communicating with a measuring instrument, which is in communicating connection with a sensor for reception of the physical variables. The computer receives the physical variables, which are collected in the measuring instrument, as a function of time of the at least one sensor; filters the physical variables as a function of time to generate filtered signals, and creates from the filtered signals a highly resolved envelope representing a signal level of the physical variables; and determines a first limit value curve and a second limit value curve, the position of which is variable in a direction of an ordinate, and the first limit value curve represents the limit value.

摘要： A method of controlling a regulating transformer with a settable translation ratio, switchable between a first and second AC-mains includes the following operations: detecting phasor data of phasors of the first and/or second AC-mains; determining an equivalent circuit diagram with equivalent circuit diagram parameters for the first AC-mains; determining a load model with load model parameters for the second AC-mains; determining the equivalent circuit diagram parameters and the load model parameters from the phasor data; and when switching over to a desired translation ratio is to take place: predicting a working point of the second AC-mains for the desired translation ratio; checking a stability criterion in the second AC-mains for the predicted working point; and switching over to the desired translation ratio is carried out upon the stability criterion being fulfilled, but otherwise not switching over to the desired translation ratio.

摘要： An electrical system (1) for a three-phase alternating current network, comprising a transformer (20U, 20V, 20W) with a primary side (30U, 30V, 30W) and a secondary side for each phase (U, V, W) of the alternating current network; a separate transformer housing (60U, 60V, 60W) for each transformer (20U . . . W); and a switching assembly (100) connected to the transformers (20U . . . W); wherein the primary side (30U . . . W) and/or the secondary side has a main winding (21, 22, 23) and a regulating winding (31, 32, 33) in each phase; the switching assembly (100) is designed such that it can connect each regulating winding (31, 32, 33) with each of the main windings (21, 22, 23); and the switching assembly (100) is arranged in one of the transformer housings (60U . . . W) or in an own switch housing (70).

摘要： The invention generally relates to power converters, and more particularly to a communications method for controlling at least one power switching device of a power converter, a communications system for a power converter, and a power converter comprising the communications system. For example there is provided a communications method for controlling at least one power switching device of a power converter, the method comprising: inputting a signal to a transmit end of a communications link; inputting data to the transmit end of the communications link; determining whether the signal comprises a transition; when said determination indicates that the signal comprises a transition, transmitting the signal comprising the transition into a communications channel of the communications link, wherein the transmitted signal is delayed by a predetermined time delay relative to the inputted signal, said predetermined time delay to allow said determining; transmitting the data on the communications channel, wherein when said determination indicates that the signal comprises a transition the transmitting the data is delayed until after said transmitting the signal; and if the signal has been transmitted, receiving the transmitted signal at the receive end of the communications link and controlling at least one said power switching device dependent on said received signal.
