Calibration Proposal for UHF Partial Discharge Measurements at Power Transformers
Energies, 2019 The continuous, non-intermitted service of electrical grids relies on the reliability of their assets, e.g., power transformers. Local insulation defects can result in serve failures such as breakdowns with severe subsequent costs. The prevention of such

Validation of Compact-Standard Antenna Method for Antenna Calibration above 1 GHz [PDF]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2019 In this paper, we propose a compact-standard antenna method (C-SAM) for antenna calibration above 1 GHz. The test-site evaluation of the fully-anechoic room (FAR) condition satisfied the free-space conditions.
