An UWB Printed Antenna for Partial Discharge UHF Detection in High Voltage Switchgears
As important fundamental equipment, high voltage switchgears are widely used in electric power systems and directly relative to the power reliability and quality. Partial discharge (PD) online monitoring is one of the most effective methods used for insulation testing and diagnosis in high voltage switchgears and power systems. This paper proposes a unique ultra-wide-band (UWB) antenna with hig...
متن کاملDesign of Meander Antenna for UHF Partial Discharge Detection of Transformers
Ultra high frequency (UHF) partial discharge (PD) detection approaches take advantages of strong anti-interference ability, and have been considered as a promising technology for online monitoring PD signals. This paper presents a meander antenna with wide frequency band and small size for UHF PD detection in power transformers. The optimal geometric parameters of the meander antenna were obtai...
متن کاملDesign of a New Built-in UHF Multi-Frequency Antenna Sensor for Partial Discharge Detection in High-Voltage Switchgears
In this study a new built-in ultrahigh frequency (UHF) antenna sensor was designed and applied in a high-voltage switchgear for partial discharge (PD) detection. The casing of the switchgear was initially used as the ground plane of the antenna sensor, which integrated the sensor into the high-voltage switchgear. The Koch snowflake patch was adopted as the radiation patch of the antenna to over...
متن کاملCharacteristic Analysis of Partial Discharge Detection in GIS
Abstract Partial discharge (PD) detection is a valuable method for the estimation of GIS condition, and the PD mapping is benefit for GIS defects identification. To investigate the PD characteristic of the GIS model, this paper simulates different PD maps of various fault simulations, and the characteristics of PD map is acquired by the pulse amplitude, phase and the discharge density to identi...
متن کاملPartial Discharge Diagnosis on GIS Based on Envelope Detection
In order to detect and identify the defects on GIS, the ultra-high frequency envelope detection circuit and high-speed data acquisition system was designed, and the tests of five typical defects for GIS were made in the laboratory and the envelope signal was acquired based on Ultra-high frequency (UHF) envelop detection circuit. And wavelet denoising technique was used to reduce the white noise...
