摘要： The power system may include a main circuit arrangement having a power source, a load and a circuit breaker. The power system may additionally include an energy harvesting circuit arrangement connected to the main circuit arrangement. The energy harvesting circuit arrangement may include an operating switch and an energy harvester. The power system may also further include a trigger mechanism, which may be configured to, when detecting a current above a predetermined value in the main circuit arrangement, trigger the circuit breaker to switch from a closed mode to an open mode. The trigger mechanism may also be configured to trigger the operating switch to switch from an open mode to a closed mode for a predetermined duration, and back to the open mode after the predetermined duration, thereby storing electrical energy in the energy harvester.
