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: A system for detecting and indicating partial discharges and voltage. The system allows capturing signals from the electric power system and/or the electrical equipment thereof, and detecting and indicating the presence or absence of partial discharges and voltage, which allows carrying out a quick and simple inspection in order to prevent faults in the distribution elements, preventing risks and performing suitable installation maintenance.

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: The present invention relates to a high-voltage insulated adaptor (100) for application at a point of connection between a piece of high-voltage electrical equipment (6) and at least one measuring, control and protecting means (8), which allows connecting the measuring, control and protecting means (8) with at least one bar (10) of the main set of bars of the high-voltage electrical equipment (6), regardless of the type of element (5) for electrical connection existing in the high-voltage electrical equipment (6), where the adaptor (100) additionally comprises at least one anchoring means (9) securing the installation of the assembly formed by the insulating body (1) and the measuring, control and protecting means (8) on the bushing (5) for electrical connection corresponding to at least one bar (10) of the main set of bars of the high-voltage electrical equipment (6).
