In the first part of this two-part paper, a turret-electrode antenna was introduced and designed to overcome obstacles in its use. In this part of the paper, the application of the proposed antenna in PD measurement on power transformers is investigated in detail. A comparison between a commercially available UHF probe and the proposed antenna is performed in respect to detection frequency range and sensitivity, detection of low radiant PD source and possibility of localization and calibration. A study on the feasibility of distinguishing external disturbances from internal PD sources using the turret-electrode antenna is also presented. Results show great potential of the proposed antenna which makes the UHF method more practical and productive for power transformers.
