ABSTRACT: Dynamic capacity increase in high voltage electric power
transmission line is currently the most economical method for solving electric
power transmission bottleneck nowadays. DS18B20 temperature
sensor is applied to the dynamic capacity increase of high voltage transmission
lines to measure the conductor temperature and ambient temperature. The paper
is focused on the experiment of DS18B20 both in the laboratory and outside. From the
result of the lab temperature measurement data analysis, using 4
DS18B20’s is the most suitable plan, considering both accuracy and economical
efficiency. In the experiment outside, we get four groups of conductor (uncharged)
temperature and four groups of ambient temperature. The data proved
that DS18B20 has good stability, and small measurement error. It is suitable
for measuring the temperature of conductor and ambient in dynamic capacity increase,
and helpful to improve the accuracy of the calculation of capacity increasing.
