A useful technique to estimate the degradation of insulation in high voltage (HV) installations is the measurement of partial discharge (PD). Free-space radiometric (FSR) detection of PD is a relatively new technique. Several types of PD emulator sources have been constructed: two internal PD emulators and a floating electrode emulator. The emulators have been simulated using the CST Microwave Studio...
Partial discharge is measured simultaneously using free-space radiometry (FSR) and a galvanic contact measurement technique based on the IEC 60270 standard. Several types of PD (Partial Discharge) sources are specially constructed: two internal PD emulators and an emulator of the floating-electrode type. The excitation applied to the source is AC and the radiated signal is captured using a wideband...
Partial discharge (PD) is measured simultaneously using free-space radiometric (FSR) and a galvanic contact measurement technique based on the IEC 60270 standard. The PD source is an emulator of the floating-electrode type. The radiated signal is captured using a biconical antenna. A method of estimating absolute partial discharge (PD) activity level from a radiometric measurement by relating effective...
