Abstract
This paper present a PD localization study based on acoustic PD signal. First, the PD localization was developed utilizing Acoustic Emission Sensor (AES). A test tank was fabricated whereby the PD was generated through needle-sphere electrode configuration. The electrical PD was measured through Impedance Matching Circuit (IMC). Based on the measured acoustic PD signal, the localization was carried based on Time of Arrival (TOA) method. The time between electrical and acoustic PD signals was used to determine the time of travel. It is found that the PD can be approximately localized through the AES system and TOA approach. At least 2 AES signals intersect at the PD location in the current study.
