A device for monitoring the flow of a current in a load powered by a DC voltage source and a method for the implementation of the device. The device includes, series-connected with the load, a first device to detect the presence of an alternating current and a second device to interrupt the current flowing in the first device while keeping the current substantially direct in the load. Advantageously, the second device includes at least one first electronic switch series-connected with the load and with the first device, the first electronic switch being controlled so as to set up the alternating current in the first device. A method of implementing the device cyclically opens and closes the electronic switch while making the second device operable or inoperable, also cyclically, to keep the current substantially direct in the load and let the current flowing in the load pass through the second device only periodically.
Method for monitoring flow of a substantially direct current in a load, utilizing a device comprising, series-connected with the load, a current detector configured to detect a presence of an alternating current, a first switching mechanism configured to interrupt a current flowing in the current detector, and a second switching mechanism configured to short-circuit the current detector and first switching mechanism, and the method comprises performing cyclically, as long as the load is powered:
