| Summary: | Antennas can be used as a sensor for detecting and measuring partial
discharges (PD) by receiving the electromagnetic waves emitted by the PD
phenomenon, and using the captured signal, the size of the observed PD may be
determined. Antenna sensors for PD measurements have been studied quite
extensively at the High Voltage and High Current Laboratory of ITB in the last
decade, resulting in a number of antenna designs. One of the previous studies done
by a member of the lab has summarized the performance results of the designs
available and ranked them according to their bandwidth. In this study, several of
the antenna models that have previously been studied in the lab will be retested to
characterize the PD measurement results of these antennas as well as to evaluate
their functionality as a PD sensor. The antennas tested include a microstrip
antenna, bowtie antenna, log periodic antenna, cube antenna, and loop antenna.
Based on the tests done, the best antenna for PD detection and measurements is the
microstrip antenna. However, the microstrip antenna can still be improved as it
currently has unsatisfactory sensitivity for negative PDs, an oddity with the polarity
of its measurement, and quite high levels of background noise. |
