  • Phase and zero-sequence current sensing modules mounted together on a cable bushing
    Patent number: 11189421
    Abstract: A current sensing modular system, which allows sensing the phase current and/or the around-fault or zero-sequence current, having to that end at least a first module having at least one phase current sensor embedded therein and a second module having a zero-sequence current sensor embedded therein. The first module is independent of the second module, both modules being installed directly in the connection elements, i.e., in the connection point between at least one bushing and at least one connector of at least one grid cable.
    Type: Grant

  • High-voltage lead-in insulating device
    Patent number: 10908185
    Abstract: The lead-in insulating device (1) of the present invention allows the passage of a live conductor (5) through a wall (18) of high-voltage electrical equipment (14), and in turn allows sensing voltage and current, for which purpose it comprises at least two electric shields (6, 7) and at least one current measurement element (12, 13), installed such that they allow detecting the presence/absence of voltage and precisely measuring the voltage and current, as well as a simple and rapid installation/removal thereof.

  • PHASE AND ZERO-SEQUENCE CURRENT SENSING MODULES MOUNTED TOGETHER ON A CABLE BUSHING
    Publication number: 20190287718
    Abstract: The present invention relates to a current sensing modular system, which allows sensing the phase current and/or the ground-fault or zero-sequence current, having to that end at least a first module (7) comprising at least one phase current sensor (5) embedded therein and a second module (8) comprising a zero-sequence current sensor (6) embedded therein. According to the invention the first module (7) is independent of the second module (8), both modules (7, 8) being installed directly in the connection elements, i.e., in the connection point between at least one bushing (2) and at least one connector (4) of at least one grid cable (3).
