摘要： A clamp for measuring a ground loop current includes a first jaw secured to a fixed support and a second jaw pivotally mounted on the fixed support, and pivotable between a position closing the clamp and an open position, and an elastic element for returning the movable jaw to the closed position. The clamp includes a device scaling down the force required for opening the clamp, by application of the force to a trigger. The device is mounted between the elastic return element and the trigger, upon opening the clamp.

摘要： A single-torus ohmmeter for measuring a loop impedance Zx, includes a single transformer having a primary winding of Np coils and a secondary winding of a single coil forming the measurement loop, in which, to compensate for a stray induction produced by an AC leakage current circulating in the measurement loop without canceling a measurement current Ip generating an alternating induction of constant average value for the measurement of the loop impedance Zx, the transformer includes a second secondary winding of Na coils whose output voltage Ub representative of the AC leakage current is delivered to a processing module providing a voltage intended to be added to an alternating measurement voltage Vp in an adder delivering the current to be injected into the primary winding after passage through a voltage-current converter.

摘要： A process for identifying the usage of electrical equipment connected to a power supply grid has an asynchronous motor coupled to a charge including identifying the usage of the electrical equipment by using an electrical signature of this equipment. The electrical signature is determined in a previous step and consists of a limited and predetermined set of characteristic frequencies and their harmonics obtained from the only information featuring on the identification plate of the asynchronous motor, and from visual inspection of the charge and its method for coupling to the asynchronous motor.

摘要： A switch mode power supply comprises a power converter including a transformer having a primary winding connected to a primary circuit, and a secondary winding connected to a secondary circuit delivering an output voltage to a load. The primary circuit comprises a controller for operating a switch element to chop the current flowing in the primary winding to transfer energy selectively to the secondary winding. The secondary circuit comprises a storage capacitor delivering the energy to the load, a first regulator receiving the output voltage and delivering a first control current for the controller via an isolator element, and a second regulator receiving an auxiliary output voltage that is an image of the output voltage and delivering a second control current for the controller. The second control current is added to the first control current to avoid any interruption in the chopping of the current flowing in the primary winding.

摘要： Portable device for a contactless measurement of a current passing through an electrical conductor, the device including a measuring module and a processing module, the measuring module, configured to be held by an operator in contact with the conductor in a plane substantially orthogonal to this conductor and without clamping this conductor, including one or two pluralities of magnetic field sensors, and the processing module being configured to perform a determined linear combination of the plurality of signals delivered by one or the two pluralities of magnetic field sensors, so as to perform an angular spatial filtering isolating the current to be measured from other disturbing currents passing through other conductors.
