摘要： In one example, a ground fault circuit interrupter is provided. It may include a current imbalance detection circuit configured to provide a leakage signal and a main processing circuit including a processor. The leakage signal may correspond to a current imbalance between a supply path and a return path. The processor may be configured to receive the leakage signal, analyze a time pattern of the leakage signal, determine whether a ground fault exists based on analysis of the time pattern, and generate a first trigger signal if the ground fault is determined to exist. The ground fault circuit interrupter may further include a back-EMF detection circuit configured to provide a back-EMF detection signal. Methods for detecting and responding to a ground fault are also provided.

摘要： The present disclosure relates to a reverse grounding protection circuit and a ground fault circuit interrupter. The reverse grounding protection circuit may include a power supply circuit, a leakage signal amplifying circuit, a leakage grounding detection circuit, a power supply indicator circuit, a manual detection circuit, a tripping mechanism control circuit, a reverse connection detection and execution circuit, and a power-on driving signal generating circuit. A ground fault circuit interrupter may comprise an interrupter body and a reverse grounding protection circuit in the interrupter body. The practice of the present disclosure may avoid the risk from reverse connection of the ground fault circuit interrupter and output of power of reverse connection, and thus improve safety of the ground fault circuit interrupter.

摘要： In one example, a hybrid circuit interrupter may include a three-coil architecture, first coil circuitry, leakage detection circuitry, and a main processing circuit including a processor. The three-coil architecture may include a coil housing, three coils, and a plurality of coil assembly conductors. The coils may be disposed within the coil housing. The coil assembly conductors may be at least partially disposed within the coil housing. The first coil circuitry may be connected to the first coil and may generate first coil signals. The leakage detection circuitry may be connected to the other two coils and may generate a leakage signal. The processor may receive the first coil signals, receive the leakage signal, determine whether an arc fault exists based on the first coil signals, determine whether a ground fault exists based on the leakage signal, and generate a first trigger signal if a fault is determined to exist.
