  • Patent number: 12081020
    Abstract: A method for controlling an output voltage of at least one transformer in a power grid comprises providing the one transformer(s) with a power electronics converter and an output voltage controller, determining a grid frequency, comparing the grid frequency with a reference value, producing an error signal, applying the error signal as feedback to the controller, and generating a control action to cause the controller to change the output voltage of the transformer comprising a power electronics converter. The power electronics converter is an AC-AC converter, and the method comprises connecting the AC-AC converter to either a primary side or a secondary side of the transformer. The AC-AC converter has a first AC side and a second AC side and the method comprises connecting two terminals on the first AC side to a winding of the transformer, and connecting the second AC side to an external circuit line.

  • Patent number: 11979326
    Abstract: Systems and methods are disclosed for analyzing traffic received at a network visibility node to determine traffic levels relative to capacity at tools communicatively coupled to the network visibility node and throttling traffic when the traffic levels exceed tool capacity. In an illustrative embodiment, streams received at a network visibility node are analyzed to predict a traffic level) for a given traffic flow. The predicted level of traffic for a given traffic flow is used to decide whether to forward traffic associated with the given traffic flow to a tool port of the network visibility node that is communicatively coupled to an external tool.

  • Publication number: 20220416532
    Abstract: The present invention relates to a residual current circuit breaker, RCCB, (100) for an electrical circuit (300). The RCCB comprises a first switching device (106) and a second switching device (140) coupled in series with each other between the power supply (302) and the load (304). The first switching device (106) is configured to switch into an OFF mode, in which no current is fed to the load (304), upon detecting that a value of a current i fed to the load (304) is larger than a switching current is of the first switching device (106). The second switching device (140) is configured to switch into an ON mode, in which the load (304) is short cut, upon detecting a leakage of the current i fed to the load (304). Thereby, a novel RCCB architecture is provided. When a current leakage is detected a short cut is introduced which means that the voltage will be zero over the load and no person will be harmed by the current in the circuit.
