This document covers internal arc-fault control devices, hereinafter referred to as IACD, which are intended to: 1. -detect internal arc-faults in low-voltage switchgear and controlgear assemblies, by processing (at a minimum) the optical effect of an internal arc-fault, and 2. -operatemitigation device(either external or combined) in order to minimize the effects of the internal arc-fault (see Figure 1).
