Acoustic localization during Factory Acceptance Testing
This advertorial from SGB-SMIT introduces a fiber-optic-based acoustic localization system capable of simultaneously reading up to 32 EMC-immune sensors.

Factory Acceptance Testing (FAT) of power transformers includes the Induced Voltage Partial Discharge (IVPD) test, which ensures insulation integrity by identifying potential partial discharge (PD) sources. Internal PD sources can threaten long-term reliability and must be accurately located. Traditional electrical measurement techniques can narrow the PD location but lack the resolution for precise pinpointing. Acoustic localization, which detects the shockwaves emitted by PD events, offers a promising solution for this purpose. This advertorial from SGB-SMIT introduces a fiber-optic-based acoustic localization system capable of simultaneously reading up to 32 EMC-immune sensors. The approach enhances PD source detection and localization efficiency and reduces transformer inspection time. Two practical case studies illustrate the method’s application and effectiveness in a production environment.
