摘要： An method for automatically testing an arc flash detection system by periodically or continually transmitting electro-optical (EO) radiation through one or more transmission cables electro-optically coupled to respective EO radiation collectors. A test EO signal may pass through the EO radiation collector to be received by an EO sensor. An attenuation of the EO signal may be determined by comparing the intensity of the transmitted EO signal to an intensity of the received EO signal. A self-test failure may be detected if the attenuation exceeds a threshold. EO signals may be transmitted according to a particular pattern (e.g., a coded signal) to allow an arc flash detection system to distinguish the test EO radiation from EO radiation indicative of an arc flash event.

摘要： An electro-optical (EO) radiation collector for collecting and/or transmitting EO radiation (which may include EO radiation in the visible wavelengths) for transmission to an EO sensor. The EO radiation collector may be used with an arc flash detection device or other protective system, such as an intelligent electronic device (IED). The arc flash detection device may detect an arc flash event based upon EO radiation collected by and/or transmitted from the EO radiation collector. The EO radiation collector may receive an EO conductor cable, an end of which may be configured to receive EO radiation. A portion of the EO radiation received by the EO radiation collector may be transmitted into the EO conductor cable and transmitted to the arc flash detection device. The EO radiation collector may be adapted to receive a second EO conductor cable, which may be used to provide redundant EO transmission and/or self-test capabilities.

摘要翻译：一种通过周期地或连续地通过电光耦合到相应的EO辐射收集器的一个或多个传输电缆来传输电光（EO）辐射来自动测试电弧闪光检测系统的方法。测试EO信号可以通过EO辐射收集器以由EO传感器接收。可以通过将所发送的EO信号的强度与所接收的EO信号的强度进行比较来确定EO信号的衰减。如果衰减超过阈值，则可以检测到自检失败。可以根据特定模式（例如，编码信号）来传输EO信号，以允许电弧闪光检测系统将测试EO辐射与指示电弧闪光事件的EO辐射区分开。
