Nondestructive and noncontact dielectric measurement methods for transformer oil using free-space microwave measurement system in 19 25 GHz frequency range
Nondestructive, noncontact and real time evaluation of dielectric properties of low-loss liquids are important for applications such as service-aged transformer oil, biomedical, remote sensing and design of radar absorbing material. Free-space methods were developed to measure dielectric proper...

description |
Nondestructive, noncontact and real time
evaluation of dielectric properties of low-loss liquids are
important for applications such as service-aged transformer
oil, biomedical, remote sensing and design of radar absorbing
material. Free-space methods were developed to measure
dielectric properties of low-loss liquids at microwave
frequencies. Metal-back method was developed for Freespace
Microwave Measurement system (FSMM). The
purpose of this research is to measure the dielectric
properties of transformer oil by using free-space microwave
measurement system between 18 – 26 GHz (K-band), to
compare measured results with published results for
transformer oil and to collect the variation values of
dielectric properties in microwave frequency between 18GHz
to 26GHz (k-band). FSMM system consists of spot focusing
horn lens antennas, mode transitions, coaxial cables and
vector network analyzer (VNA). Dielectric constants and loss
factors were measured for new transformer oil and all results
close agreed with published data. It is observed that metalback
method is suitable for dielectric measurement of
transformer oil. |
