Research Status and Development Prospect of Optical Fiber High-Temperature Sensors

Accurate temperature measurement needs in both research and industry have become more demanding and traditional temperature measurement technologies are struggling to keep up. Optical fiber thermometers have many unique advantages and are an option with much potential in the area of high temperature measurement. Research shows that fiber optic temperature sensors are capable of making accurate and precise measurements in a wide range of harsh conditions where other measurement technologies cannot and are a cost effective option in situations where traditional measurement technologies are currently used. Several typical high temperature fiber optic sensors are discussed in detail, focusing on the principle of operation, advantageous characteristics, and recent research developments, with the aim of aiding in further work with fiber optic thermometers.

Study of Efficient Electrical Failure Scheme

This paper mainly studies on Reasons for generating electrical fault .It deeply studies and analyzes the application of thermal imaging cameras. Thermal imaging cameras display clear image, data collection method is simple, timely and accurate infrared imaging technology to find hot hidden, to make a reliable forecast of the early failure of the electrical equipment defects and insulation performance,so that the early failure determination of electrical device becomes easy and changes traditional preventive maintenance to predicting maintenance.The thermal imaging for its safe ,accurate temperature measurement,and many other advantages more and more widely used.The research of this paper has some theory guidance and high application value.
