“…The history of employing an antenna as a UHF sensor for PD detection can be traced back to the middle 1990s [7,8]. The technology has recently been used for PD online monitoring [5,9] and PD detection in systems such as sulfur hexafluoride (SF6) insulated switchgears [10,11] and gas-insulated substations [12].…”

Abstract-Partial Discharge detection techniques strive to ensure a safe and reliable power network by preventing power failure. In this work, electromagnetic sensing of partial discharge, in air-insulated medium voltage switchgear (Type D24-121114 of Driescher) is considered. The partial discharges are approximated by Gaussian sources. A versatile broadband sensor for detecting two major types of partial discharge was designed and optimized. The antenna has low return loss and high gain over the frequency band of corona discharge, 0.75-0.9 GHz and dry band arcing, 1.25-1.4 GHz. The horn antenna is incorporated into the medium voltage switchgear for detecting partial discharges. The analysis of the electromagnetic field distributions generated by partial discharges in switchgear is coupled with the sensing efficiency of the horn antenna. The results indicate a good correlation between the intensity, location and frequency band of partial discharge and their sensing. This study provides the foundation for a dual band detection system of partial discharge in switchgear systems.

“…Partial discharge (PD) measurement as an effective condition monitoring technique can detect incipient failures and prevent unexpected accidents of MV switchgears [1]. There are many ways to detect PDs, however sensors should be installed inside the switchgear when applying gas, light or heat method.…”

The principle of detection of partial discharge in MV Metal-Clad Switchgears utilizing Transient Earth Voltage (TEV) method is introduced and some problems in application of the traditional PD detection systems are summarized and analyzed. After that, an improved PD detection system is proposed and established with an advanced technique. The technique involves use of energy method to determine time difference among multiple signals and external trigger method to realize phase integrity during data acquisition process. Laboratory experiment and site tests are conducted and it is proved that the improved detection system is of great effectiveness in PD location and interference identification.

“…PDM methods are divided into five major categories: electric, electromagnetic, acoustic, optical, and chemical method [1]. Radio sensing systems for detecting PD have been developed for power equipment [3–14]. It is reported that PD in a gas‐insulated switchgear (GIS) was detected with sensitivity of several pC by receiving the ultra‐high frequency (UHF: 300 MHz to 3 GHz) band EM waves emitted from PD [1,2].…”

“…It is reported that PD in a gas‐insulated switchgear (GIS) was detected with sensitivity of several pC by receiving the ultra‐high frequency (UHF: 300 MHz to 3 GHz) band EM waves emitted from PD [1,2]. The sensitivity of PD sensor in a Cubicle Type GIS is investigated in the frequency range from the very high frequency (VHF: 30–300 MHz) to UHF [14]. The frequency spectrum of the EM waves emitted from PD has resonant frequencies depending on the shape and size of a metallic enclosure [13,14].…”

Superheterodyne spectrum analyzer (SA) has been widely used for receiving EM waves emitted from partial discharge (PD) because of its high sensitivity. Generally, resolution bandwidth is shown as a measurement parameter because the pulse response depends on the receiver's bandwidth. In this paper, we measure the impulse bandwidth of SA and describe the effect of the impulse bandwidth of SA on the measurement of EM waves emitted from PD in multipath‐rich environment. The results showed that the field strength of the EM waves emitted from PD is proportional to the impulse bandwidth higher than about 200 kHz and signal‐to‐noise ratio (SNR) increases with the impulse bandwidth as in the measurement of pulsed RF signals. © 2011 Institute of Electrical Engineers of Japan.
