Arc-Flash Detection  
PGA-LS20 Series  
Fiber Optic Sensor  
Description  
The PGA-LS20 series is an arc-detection, fiber-optic sensor that is designed to detect arcs along its entire length. This  
sensor is meant to be installed with the fiber along the back wall of switchboards to form the detection range across all  
compartments with just one sensor. The sensor is positioned to allow direct line of sight to all powered connections where  
an arc could develop. The sensor is capable of detecting the light from an arc flash from all angles. The detection radius is  
dependent on the arc power. The sensor is calibrated at the factory for 60 cm (24 in) of fiber in each monitored  
compartment. When using a fiber-optic sensor in compartments with less than 60 cm (24 in) of fiber, the sensitivity may  
have to be adjusted so that the sensor will detect arcs of 3 kA or more. This fiber-optic sensor and the arc-flash relay  
provide superior protection against the damaging effects of arc flashes and improve the lifespan of electrical equipment  
as well as the protection of personnel.
