<p>PURPOSE:To accurately measure a conductor temperature with no correction by the temperature required by storing an optical fiber wire temperature sensor in a metal tube twisted to be mixed and built in the inside of a twisted wire conductor. CONSTITUTION:In a power cable, an optical fiber temperature sensor 13' is mixed to be twisted and built in a segment conductor 3' with a twisted element wire 3a constituting partly this segment conductor 3'. Since heat is directly transmitted to the optical fiber temperature sensor 13' from the segment conductor 3', a temperature of the conductor 3' can be directly measured.</p> |
