Schematic diagram of fiber optic arc light sensor
(a) The circuit design for the Arc-Flash point sensor
In this work, a loop sensor for Arc-Flash detections has been developed in order to trip a circuit breaker within 2.5 ms after an Arc-Flash event.
APPLICATION GUIDE
1.2 Optical Sensors optical sensors. These sensors have been designed to have a wide detection angle and provide the correct sensitivity for an arc flash. LEDs on the relay and on the sensors indicate
SEL Arc-Flash Detection (AFD)
Point sensors intercept some of the light created by the arc flash at a single location, such as inside a breaker compartment. The light is brought to the relay via one of the fiber-optic cables connected to
