    Abstract: A method and apparatus for determining a voltage potential in a power switching device. The method and apparatus uses a conductive shield surrounding a coil positioned around a connector in a power switching device. The coil is used to provide a current measuring device within the power switching device. The combination of the shield, connector and the dielectric between them forms a capacitor, which is the high voltage leg of a capacitive voltage divider circuit. The capacitive voltage divider has a low voltage leg made of one or more capacitors. The capacitors of the low voltage leg may be removed in order to adjust the output of the capacitive voltage divider. The output of the voltage divider circuit is measured, converted and displayed to a user.

    Abstract: A method and/or apparatus for measuring current in a high voltage (HV) current carrier generates a low voltage signal proportional to the current in the HV carrier and applies this signal to an integrated-optic voltage sensor located in the HV environment adjacent to the HV current carrier to produce a modulated optical signal representative of the current being measured. The optical signal from the integrated-optic voltage sensor is conducted to a low voltage (LV) environment insulated from said HV environment and processed to provide a second electrical signal. One of the electrical signals is integrated so that an output signal of the required accuracy is available form the system.

    Abstract: The invention concerns a coil comprising an insulating support (1) and a conductor wire (3) coiled on the support of an initial end (1l) to a terminal end (1F) to form a first winding (5) with contiguous turns (5A). The conductor wire is then coiled on the insulating support (1) of the terminal end (1F) towards the initial end (1l) of the support to form a second winding (7) with contiguous turns (7A) superposed on the first winding (5). The second winding (7) is centred relative to the choking coil centre to compensate the large turn formed by the choking coil itself, thereby protecting the choking coil against stray magnetic fields. Advantageously, a second conductor wire (4) is coiled around the support to form a third winding (9) with turns (9A) superposed on the first and second windings, and for injecting a test current to calibrate the choking coil in laboratory or in situ simply and economically.
