    Abstract: 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.

    Abstract: A method of and an electrical fault monitoring apparatus for mon itoring an electrical load in an alternating current electrical installation are disclosed. An input terminal is connected to the electrical load to receive current/voltage input signals associated with the electrical load. A monitor in communication with the input terminal, monitors the input signals. An operator pre-defines threshold settings suitable for the particular load. A comparator is responsive to the monitor and compares the monitored input signals with the threshold settings and triggers an event if the monitored input signal violates a threshold setting. An output signal is then produced which activates ancillary equipment controlling the supply of power to the load. Tests are conducted at predetermined intervals and a record log is automatically kept of the tests done.
