Abstract:
1. An apparatus, comprising: an electro-optical (EO) radiation collector comprising an EO radiation receiving area; a first EO conductor having an end secured within the EO radiation receiving area; and a second EO conductor, wherein the EO radiation collector is configured to reflect at least a portion of test EO radiation transmitted through one or more of the first EO conductor and the second EO conductor into one or more of the first EO conductor and the second EO conductor, and wherein an arc flash detection device determines an attenuation based on EO radiation collected by one or more of the first EO conductor and the second EO conductor in response to the test EO radiation, and determines a result of a self-test operation based on the determined attenuation.
