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： A system for transmitting status information from a first location to a remote second location includes a monitoring device at the first location for monitoring the state of a plurality of relays or other devices that are capable of being in either an active or inactive state. The monitoring device produces a digital signal representative of the state of the relays. A first memory storage device contains a table of digital codes arranged so that a unique code is associated in a predetermined manner with each relay in each state. A processor is provided for processing the digital signal from the monitoring device and for accessing the table to retrieve the code associated with the present state of each relay. The processor also produces a first signal indicative of a change of state of any relay from the inactive to the active state. A transmitter transmits the codes retrieved from the processor in a predetermined sequence. An interrupt device is included that interrupts the transmission sequence in the presence of the first signal to cause the immediate transmission of the code associated with the relay that has changed from the inactive to the active state. A receiver at the remote second location receives the transmitted codes and verifies their validity by comparing the received codes to a table of expected codes contained in a second memory storage device. If the code received is valid, a decoder determines the relay and state represented and formulates and outputs a control word representative of the state of the monitored relays. If the code is invalid, an alarm signal is generated that inhibits the output of a control word. Once an alarm signal is generated, it is maintained until a valid code is received for each of the monitored relays without the reception of an intervening invalid code. Preferably, the transmission and reception of the codes are accomplished under control of a digital computer operating under program control.

摘要： An arc flash validation unit may generate stimulus to be received by an arc flash detection unit (AFDU) and observe the response of the AFDU thereto. The response of the AFDU to the stimulus may allow for validation of the AFDU (e.g., validation that the AFDU is operating as expected). In addition, the arc flash validation unit may determine the response time of the AFDU. Different types of stimulus may be provided to the AFDU, including electro-optical (EO) stimulus (e.g., visible light), current stimulus, and the like. Results of the validation may be displayed on a human-machine interface, which may display an estimate of the total energy that would be released in an actual arc flash event. The estimate may be used to define appropriate safety parameters for the equipment monitored by the AFDU.
