“…PD events in HV power equipment typically produce very short current pulses with a rise time of less than 1 nanosecond, which can emit EM waves in the GHz frequency band [5]. When this PD occurs, the UHF sensor detects the EM waves emitted by the PD [6], so the UHF antenna is a core part of the UHF PD detection system, and the performance of the UHF antenna can directly affect the detection performance of the system [7][8][9][10][11][12]. There are two approaches to detect the PD in the EM wave detection method.…”

This paper presents a ultra-high frequency (UHF) antenna for partial discharge (PD) detection and the antenna sensor can be used near a conducting ground wire. The proposed UHF antenna has advantages of easy setup and higher-frequency detection over the high-frequency current transformer (HFCT) sensor. First, a variety of loop-shaped antennas are designed to compare each near field coupling capability. Then, a new UHF antenna is designed based on the loop-shaped antenna, which has the best near field coupling capability. Finally, the proposed UHF antenna is fabricated and measured. It provides a wide impedance bandwidth of 760 MHz (740–1500 MHz). Its simple setup configuration and wide bandwidth frequency response in the UHF band can provide a more efficient means for PD detection.

“…However, the return loss of the antennas is still high and the bandwidth of antenna is still less than 300 MHz. In the previous research the author has developed the new shape bowtie antenna to detect PD in GIS [21][22]. The bowtie antenna as UHF sensor in the previous research has 295 MHz bandwidth, return loss -10 dB, and the cut-off frequency was at 1,22 GHz [21][22].…”

Partial discharge (PD) diagnostic using ultra high frequency (UHF) method has been developed recently. UHF method is the effective method in detecting electromagnetic wave emitted by PD activity in gas insulated switchgear (GIS). This paper focused on designing bow-tie antenna as UHF sensor to achieve 300 MHz bandwidth, return loss -10dB and VSWR 2. After being designed and simulated, the most optimum antenna was fabricated on a double-layer PCB with FR4-epoxy substrate. As comparison, three antennas with different flare angles were also fabricated. The antennas characteristics were measured using network analyzer. At last, the four antennas were tested in high voltage laboratory to find the most sensitive antenna in detecting PD in GIS. PD was measured in two voltage levels, 26kV and 28kV.

“…The family of Bowtie antennas [20] [21] [22] has some advantages in terms of compact size, but the impedance bandwidth is narrow to detect the total spectrum of the PD signal. Usually, the antenna bandwidth is approximately between 300 MHz and 400 MHz with one or more resonant frequencies.…”

The detection of partial discharge in GIS plays a pivotal role in preventing and mitigating severe operational failure and damage in insulation elements. Partial discharge progressively degrades the insulating medium and, as a result electrical breakdown can occur in GIS. Despite various techniques used for PD detection, the RF analysis is extensively used because it is highly reliable, has good sensitivity and the largest bandwidth.The objective of this study is to examine two applicable planar antennas for detecting the RF energy of partial discharge in GIS infrastructure. Namely, a planar complex spiral antenna and a fractal tree log-periodic dipole antenna which are located on the GIS junction of segments.
