ABSTRACT:
An arc detector comprising a voltage generator for detecting a voltage and an integrator for integrating said voltage with respect to time and generating an output signal corresponding to said integration. The arc detector also includes a discharge controller for controlling said output signal of said integrator, an amplifier for amplifying said output signal from said integrator and outputting an amplified signal; and a comparator for comparing said amplified output signal to a reference voltage and generating a detection signal based on said comparison.
