摘要： A method for loose joint detection in medium voltage switchgears with busbar joints, circuit breaker upper and lower spouts, and cable connection joints, arranged in an air insulated housing, and medium voltage switchgear itself, in order to create an effective loose joint detection with lower operating expense, but with high performance and accuracy, involves measuring actual temperatures at a first phase as a first temperature (T1), at a second phase as a second temperature (T2), at a third phase as a third temperature (T3), at predefined critical points, such as at the busbar joints, and/or at the circuit breaker upper spouts, and/or at the circuit breaker lower spouts, and/or the cable connection; and comparing temperatures in a logical dependency Ti>(Tj+dT), with i≠j, permuted with i from 1, 2, 3, and j from 1, 2, 3, and setting the alarm if the logical dependency is fulfilled.

摘要： A method is provided for determining the operating status of a spring charging motor of a LV or MV switching apparatus. The method includes acquiring a detection signal (ID) indicative of the behavior of a driving current (IMOT); processing the detection signal (ID) to calculate a steady-state detection signal (IDSS) indicative of the behavior of the driving current (IMOT) during a steady-state time interval (TSS); processing the steady-state detection signal (IDSS) to calculate data (DS) indicative of HF and LF spectral components of the driving current (IMOT); processing the data (DS) to calculate first and second harmonic distortion values (THDLF, THDHF); processing the first and second harmonic distortion values to calculate first and second output data (O1, O2), which are indicative of the variations of the first and second harmonic distortion values with respect to corresponding first and second reference values, respectively.

摘要： An accessory device for low or medium voltage electric applications includes a casing and electronic means including one or more current sensors for detecting current flowing in an electric cable. The top shell of the casing includes an external recess having a cable seat for accommodating the electric cable in a transversal position with respect to the casing. The cable seat has a cable coupling surface adapted to mechanically couple with the electrical cable. The accessory device includes a holder element mechanically coupleable with the top shell in the external recess. The holder element includes one or more holding surfaces. Each of the holding surfaces is overlapped and mechanically coupled with the electric cable, when the holder element is positioned in the external recess in a corresponding accommodating position that is selectable depending on the size of the electric cable. Each of the holding surfaces, when overlapped and coupled with the electric cable, cooperates with the cable coupling surface to hold the electric cable in a given position with respect to the current sensors.
