Temperature Testing Technology for Intelligence Electrical Apparatus Based on Fiber Grating Sensor

摘要

The on-line monitoring technology owing to fiber grating sensors is very practical in the field of intelligence electrical apparatus manufacturing and using. It can avoid the temperature monitoring method limitation which brought; by self characteristics of some electrical apparatus. The paper described the general principle of fiber grating sensors , According to the key of temperature testing technology for intelligence electrical apparatus based on distributed fiber grating sensor ，the technical architecture of an on-line temperature monitoring system in intelligence electrical apparatus is described.
