Modification of Circular Radius, Arm Patch Line Width and Power Supply Line of UWB Double Layer Printed Antenna for Partial Discharge Detection

Partial discharge is a phenomenon of electricity failure that occurs at a conductor or void. During the PD there are several phenomena that accompany the PD, other impulses, heat radiation, electromagnetic waves, mechanical waves, and chemical processes. This phenomenon is used to find out information PD. One of the measurements PD uses the UHF method i.e. with the wave sensor induced by partial discharges. An antenna was developed based on one form of the reference antenna. Changes made on five parameters (r, C, D, E, F) result are not very significant to the existing reference. Parameters change into one very significant that is the magnitude.
