Acoustic Partial Discharge fault localization in high-voltage equipment (PDL 650)

The PDL 650 is an acoustic partial discharge (PD) localization system for pinpointing the location of insulation defects in power transformers. Even at an early stage, insulation defects produce measurable partial discharges, which emit electrical and acoustic signals at the same time. The PDL 650 measures the acoustic signals with multiple sensors installed across the surface of the transformer.

Product description

Innovative defect localization

The PDL 650 software uses the time difference of incoming signals from all acoustic sensors to determine the location of an insulation defect in the transformer. The coordinates of the defect location are shown in a 3D model of the transformer. This information allows users to quickly act and take necessary maintenance actions to prevent failure.

Key features

Efficient because repairs and spare parts are predictable when failure location is known
Easy creation of reports and records
Safe due to galvanic separation of operator from high-voltage
Convenient and handy through light weight, small size and battery operation
