Beschreibung
Zusammenfassung:	According to one aspect, embodiments of the invention provide a system for monitoring at least one circuit branch coupled to a power line, the system comprising at least one first module comprising a Current Transformer (CT) configured to be coupled to the at least one circuit branch and to produce a reference signal having a level related to a current level of the at least one circuit branch, a rectifier coupled to the CT and configured to produce a rectified reference signal, a capacitor coupled to the rectifier, and a first microcontroller coupled to the capacitor and the rectifier, wherein, the capacitor is configured to store energy from the rectified reference signal, and wherein, the first microcontroller is configured to be powered by the energy stored in the capacitor and to sample the rectified reference signal to determine the current level of the at least one circuit branch.
