    Abstract: Disclosed is a device for checking withstand voltage of a connector-coupled cable. The device comprises: a pair of electrode boxes; and a control block configured to apply a start signal to a test instrument, which outputs a preset high voltage, according to an electrical state detected in each electrode box that includes: a housing whose a part of a front side is open; a conductive electrode plate mounted on an inner front side of the housing in such a way that it is rotatable around its top end; and a detection unit, mounted inside the housing with a predetermined gap from the electrode plate, to detect whether the electrode plate is rotated due to push on a lower part of the electrode plate. The electrical state is an electrical state between both terminals of the detection unit, and the preset high voltage is applied between both electrode plates.

    Abstract: A system comprising an array of solar panels, each panel including an electronic control module, wherein the panels are all connected in electrical series with each other and to a switch and to a string inverter, may be signaled to power down each panel to a safe output at its output terminals. The method includes sensing output wave forms of a module to be the result of its own DC-DC converter output or to be at variance with the expected output. Output wave forms at variance indicate that the control module is connected in electrical series with the input capacitance of the string inverter. If the output is as expected, the control module is deemed to not be connected to the capacitance of the string inverter as a result of the electrical series switch being open. The module then immediately drives its output to a safe level.

    Abstract: A sensor device for testing electrical connections using contactless fault detection is disclosed. The sensor device includes: a surface coil comprising a plurality of concentric loops disposed at a first region located away from the electrical connections. The concentric loops generate a first magnetic field passing through the electrical connections, and the first magnetic field is equivalent to that generated by a coaxial intermediate current loop adjacent to the electrical connections based on an excitation current in the surface coil. The sensor device further includes a sensor adapted to detect a second magnetic field at a second region located away from the electrical connections, wherein variations in the detected second magnetic field provide categories of performance of the electrical connections.

    Abstract: The ageing of an electrical connection installed in a vehicle is evaluated by performing a series of samplings, spaced apart from one another at predefined time intervals, so as to determine a working temperature of the electrical connection for each sampling interval, and by determining a maximum duration of the electrical connection, assuming that the electrical connection was subjected, for its entire life, to the corresponding previously determined working temperature; then, an accumulated damage of the electrical connection is calculated, by overlapping a plurality of partial damage contributions, each of which is determined for each sampling interval, by dividing this sampling time interval by the corresponding maximum duration; finally, the accumulated damage is evaluated so as to identify any criticalities.
