Abstract: The present invention relates to a system for monitoring the electric network voltage waveform, comprising: switching means (11) connected to the voltage lines (A, B, C) of a three-phase system, comprising two thyristors (T1, T2) connected to two of the voltage lines (A, B, C) and at least two capacitors (C1, C2) connected to said thyristors (T1, T2), said means (11) being configured to open and close said thyristors (T1, T2) in response to a trigger signal; means for measuring (12) the voltages in said voltage lines and at the input of said capacitors; a thyristor trigger circuit (14) for providing a trigger signal to either thyristor (DT1, DT2) when the voltage in the terminals of said thyristor (T1, T2) crosses zero; control means (13, 23) for giving said trigger order (OD) or not.

Abstract: The high-voltage connector comprises an insulating body (1, 2) with a first internal channel (3) and a second internal channel (4), configured to receive a bushing or a fixed base of a high-voltage equipment. The connector comprises at least one sensor (5, 6, 7, 8) of an electric feature at least partially embedded inside the insulating body.

Abstract: The present invention relates to an electric coupler for high-voltage DIN C type cells comprising a voltage divider, a condenser and two terminal contacts and wherein the condenser is elongated and its ends are in contact with the two terminals of the coupling device, occupying an axis parallel to the imaginary central axis of the connector passing through the two contacts and wherein the resistances of the divider are aligned and parallel to the mentioned axis of the zig-zag device. As a result of this arrangement the insulation can be assured and the field distributions of both systems are compatible with one another and with those of the DIN C connector.

Abstract: The present invention relates to a resistive voltage divider comprising a plurality n of resistive elements in a configuration wherein the angles m=n?1 between each pair of elements are between 180° and 10°, characterized in that the group of elements is supported by a dielectric the shape of which is such that it allows the creepage distance of the divider to be equal to or longer than the sum of creepage distances of the individual resistances. This arrangement allows a correct insulation of the device because it maintains the outer insulation since in the event of short-circuit the current will flow through the resistances and not through the support.
