This paper is purely a model to implement Partial Discharge (PD) detection in FPGA technology and then implement the VHDL modeled in FPGA technology for measurement of the distance test distribution pattern of the Tri-Axial magnetic probe using 3GHz ADC (ADC083000RB-Reference Board) and impulse generator. Partial discharge (PD) is a well known phenomenon that causes insulation degradation in cross...
This research involves evaluating the use of FPGA for the detection and counting of partial discharge (PD) signals in underground cables (XLPE cables). PD detection model was designed one using MATLAB and another using VHDL. The pulse signal from the cable was processed and counted using peak detector and FPGA technology. The peak detector placed inside the VHDL program when the program of PD detection...

Currently, FPGA (Field Programmable Gate Array) technology is being widely used for signal processing and control owing to its fast digital processing capability. We have recently developed successfully a high-speed data acquisition system that combines a commercial FPGA board (ML405) with the high speed ADC in ADC 083000RB that has 8 bit pairs LVDS in resolution, sampling rate of 3 GS/s and bandwidth...
This paper describes a method to determine the dielectric constant of FR4 substrate material at the operating frequency of 2.3 GHz. The method make used of computer aided engineering (CAE) tool and microstrip bandstop resonator for investigating the dielectric value of a material. In accordance with the data sheet provided by manufacturer which is 4.5 at 10 MHz, a set of preliminary dielectric values...
This paper describes the use of AD8302 evaluation board from Analog Devices in super-heterodyne millimeter wave interferometer for dielectric measurement. The measurements are performed without direct contact on the millimeter wave material. Signals from the output of two mixers in the interferometer were obtained for phase shifting analysis. They are used as inputs to the evaluation board. The output...
