Research of the technology based on fiber bragg grating for measurement of temperature rise of electrical appliances

Conference Name:2012 International Meeting on Opto-Electronics Engineering and Materials Research, OEMR 2012. Conference Address: Shenyang, Liaoning, China. Time:July 27, 2012 - July 29, 2012.A new method of using fiber Bragg gratings as the sensing elements in the measurement of temperature rises of electrical appliances is proposed in this paper. Comparing with the conventional measurement method with thermocouples, the new method can overcome problems such as electromagnetic interference, hazard of electrical leakage, etc. The characteristics and key components employed in the measuring system are analyzed and discussed. The experimental results show that the temperature rises of electrical appliances under test can be obtained quickly and accurately with the specifically designed sensors made by optical fiber Bragg gratings. 漏 (2012) Trans Tech Publications, Switzerland
