Passive Fiber Optic PD Sensor for Accurate Monitoring
OptiFender measures the acoustic emission signals of partial discharges and tracks their evolution over time with fiber optic PD sensors. The measuring principle behind the fiber optic PD sensor is based on the acoustic emission technology.
The small and completely passive sensors can be easily installed on any kind of asset, enabling the detection of close-by internal and surface partial discharges.
The acoustic emission signals acquired by the sensor is transmitted to the acquisition unit through a standard telecommunication optical fiber. The acquired data is then displayed and analyzed through the dedicated software.
