Fiber Optic Temperature Sensing in Power Systems

Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. Power systems monitoring covers all five segments of the electrical grid — generation, transmission, substation, distribution, and end-use — and temperature is the single most universal parameter across every segment and every type of equipment. Predictive maintenance using fiber optic temperature sensors is now being introduced in a wide range of fields, including steel, electric power, and chemical plants, as well as transportation infrastructure. Cost-effective continuous partial discharge monitoring for Switchgear and Transformers.
