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.

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.

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).

Abstract: Enables an electrical connection to be made in an insulated, shielded manner that makes it possible to sense a voltage presence signal, between the cable (3) and the electrical equipment with a female bushing (4) without the need to substitute or modify the high-voltage electrical equipment (2), only adding fastening elements for the adapter (1). Said adapter (1) comprises a body (6) of insulating material, equipped with a first connection end (8) configured to couple in a sealed manner into said at least one female bushing (4) of the high-voltage electrical equipment (2) and with a second connection end (9) configured to couple to the female terminal (5) of the cable (3).

Abstract: The present invention relates to a transformer substation (6) comprising high-voltage switchgear (1), a low-voltage switchboard (3) and a transformer (2) which are electrically interconnected on the upper cover (5) of the transformer (2) through a shielded direct single-pole connection. The high-voltage electric connection (4) is carried out by means of a connection device (8) which, in combination with a control/protection device (10), allows carrying out the safe and integral protection of people and property against possible malfunctions in the transformer substation (6), limiting said malfunctions and preventing disturbances of the high-voltage and low-voltage network.
