  • Arc fault detection device
    Patent number: 11769995
    Abstract: An arc fault detection device includes: a first electric line; at least one sensor for monitoring an electric current or voltage spectrum in the first electric line and outputting an analogue HF measurement signal; and an input section connected to the at least one sensor, the input section including: an input bandpass filter connected to the at least one sensor so as to filter the analogue HF measurement signal, a passband of the input bandpass filter having a predeterminable arc-frequency range so as to detect arcing effects; and a sampling mixer connected to the input bandpass filter, the sampling mixer having a sampling frequency lower than twice an upper threshold frequency of the arc-frequency range.
