Power over Fiber (PoF)   /   POF-WL240 Series Power over Fiber Smart Monitoring System

The PoF Smart Monitoring System represents a new generation of continuous monitoring systems for switchgear and other critical electrical assets, enabled by the adoption of power over fiber (PoF) technology. A laser data module (LDM) delivers laser light through a non-conductive fiber patch cord (FPC), where the transmitted laser light is converted to electricity within a sensor module to power internal sensors. The POF-WL240 series sensor modules, which can be mounted directly onto bus bars, offer continuous monitoring of bus bar partial discharge, temperature, and humidity by taking sensor readings and then transmitting the sensor data to the LDM via the FPC. The LDM then shares the sensor data with the equipment operator’s monitoring software. The PoF Smart Monitoring System’s non-conductive FPC provides very high voltage and electrical noise isolation ensuring sensor reading data integrity and accuracy. These features make it possible for the POF-WL240 series sensor modules to be placed directly on electrically noisy bus bars, therefore providing valuable monitoring data of switchgear.
