Abstract: A method for automatically testing an arc flash detection system by periodically or continually transmitting electro-optical (EO) radiation through one or more transmission cables (610,611) 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 (621). 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.

Abstract: 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 5 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 10 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.

Abstract: Se describe un método para probar automáticamente un sistema de detección de descarga por arco al transmitir periódica o continuamente radiación electro-óptica (EO) a través de una o más cables de transmisión acoplados electroópticamente a recolectores de radiación EO respectivos. Una señal EO de prueba puede pasar a través del recolector de radiación EO a ser recibida por un sensor EO. Se puede determinar una atenuación de la señal EO al comparar la intensidad de la señal EO transmitida con una intensidad de la señal EO recibida. Se puede detectar una falla de autoverificación si la atenuación excede un umbral. Se pueden transmitir señales EO de acuerdo con un patrón particular (por ejemplo, una señal codificada) para permitir que un sistema de detección de descarga por arco diferencie la radiación EO de prueba de una radiación EO indicativa de un evento de descarga por arco.

Abstract: Se proporciona un recolector de radiación electro- óptica (EO para recolección y/o transmisión de radiación EO (la cual puede incluir radiación EO en las longitudes de onda visibles) para transmisión a un sensor EO. El recolector de radiación EO se puede utilizar con un dispositivo de detección de descarga por arco u otro sistema protector, tal como un dispositivo electrónico inteligente. El dispositivo de detección de descarga por arco puede detectar un evento de descarga por arco en base en radiación EO recolectada por y/o transmitida desde el recolector de radiación EO. El recolector de radiación EO puede recibir un cable conductor EO en un extremo del cual puede estar configurado para recibir radiación EO. Una porción de la radiación EO recibida por el recolector de radiación EO se puede transmitir dentro de un cable conductor EO y se puede transmitir a un dispositivo de detección de descarga por arco. El recolector de radiación EO se puede adaptar para recibir un segundo cable conductor EO el cual se puede utilizar para proporcionar capacidades de transmisión EO redundantes y/o autoverificación.
