With the rapid development of renewable energy and smart grids, monitoring the safety of critical infrastructure such as wind farms and battery storage facilities is highly important. In these high-load industrial environments, an abnormal cable temperature is often the earliest indicator of equipment failure or fire hazards. The Distributed Fiber Optic Temperature Sensing Analyzer is a real-time, online, and continuous monitoring system based on Raman scattering and optical time-domain scattering principles
DTS technology operates using the optical fiber as both the transmission medium and the sensing element
ラマン散乱: When a pulsed laser is introduced into the sensing fiber, it interacts with the molecular thermal vibrations within the fiber core
光時間領域反射率測定法 (OTDR): To accurately localize the spatial position of a temperature reading, the system measures the time $t$ from when the laser pulse enters the sensing fiber to when the backscattered light returns to the photodetector
Designed for complex industrial monitoring environments, HERTZINNO developed the HZ-DTS-1004/1008/1016 series analyzers
ブラインドのない長距離モニタリングスポット: The sensor cable requires no power and provides a safety warning distance of up to 13 km
高精度で欠落ゼロのレポート: The system maintains a spatial positioning distance accuracy within 1 m and a temperature accuracy of ±0.5°C, ensuring a missing report rate of zero
低消費電力と履歴ストレージ: The system features low average power consumption per unit distance and includes 120GB of internal storage, which is capable of holding 5 to 10 years of history data
Due to its advantages such as resistance to electromagnetic interference and intrinsic safety, Raman distributed fiber sensing technology has significant application value in smart grids and large-scale infrastructure
In long-distance power transmission, insulation aging or local overloads cause abnormal cable temperature rises. The HZ-DTS system is suitable for underground cable monitoring, analyzing the thermal state of the entire line
Wind farms are often situated in remote locations and contain extensive underground power collection cables. Utilizing the large monitoring range of the HZ-DTS system allows for long-distance automated monitoring, realizing unattended operation for the entire wind farm network
Battery storage facilities contain dense clusters of cells that are vulnerable to thermal runaway caused by localized short circuits. Because the HERTZINNO sensor cable requires no power, it is intrinsically safe and can be routed directly through battery racks and critical electrical pathways
