    摘要： A user interface for a wireless device used to monitor multiple groups of faulted circuit indicators. Each group of faulted circuit indicators includes a radio interface unit, which is coupled to each of the faulted circuit indicators in the group. The user interface includes an identification indicator, which includes a plurality of radio interface unit status indicators, each of which corresponds to a particular radio interface unit, and which indicates a selected radio interface unit. The user interface also includes a way indicator comprising a plurality of faulted circuit indicator status indicators, each of which corresponds to a particular faulted circuit indicator coupled to the selected radio interface unit. In addition, each radio interface unit status indicator indicates whether a particular radio interface unit coupled to a faulted circuit indicator is asserting a fault condition.

    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： A system and method for monitoring the rotation of a generator rotor. The monitor uses a light beam directed toward the rotor to detect a marking thereon, and generates an electrical pulse when the marking is detected. The time between the pulse and a reference point (such as a zero crossing) of the signal waveform from the terminals of the generator may be used to calculate the power angle of the generator. The system is adaptive in that it can account for new markings on the rotor. The system may be connected to a network so that power angles from various generators on the electrical network may be compared. The system may further be connected to a common time source such that a time stamp may be applied to the power angles from various generators, allowing for more accurate comparison of the power angles.
