  • Device and method for measuring a current
    Patent number: 7227347
    Abstract: A device and method for current measurement in a conductor and, in particular, a method to feed the devices of the invention in order to interpret the information provided. The method is based on the exploitation of discrete sampling of the information provided from the devices of the invention and allows the feeding of these devices to be modulated in order to activate the devices only when necessary.

  • Device for supplying an electronic protection device to be used in a low-voltage circuit breaker
    Patent number: 7145421
    Abstract: A supply device (1) for an electronic protection device to be used in a low-voltage circuit breaker. The supply device basically comprises a primary conductor (11), a secondary winding (12), a first magnetic circuit (10), and at least one second magnetic circuit (20). The first magnetic circuit (10) is such as to surround said primary conductor (11), which is related to a phase protected by the protection device; at the same time, the first magnetic circuit (10) constitutes the core of said secondary winding (12) that is used for supply of the protection device. The second magnetic circuit (20) is structurally separated from the first magnetic circuit (10), but is operatively connected thereto for subtracting part of the first magnetic flux generated within it by the current circulating in the primary conductor (11).
