Description

Transformer Testing – Partial Discharge

The AE-150 detects and locates Partial Discharges & Hot Spots in power transformers. This is done by analysing ultrasonic waves produced by a breakdown of the electrical insulation or high energy heat events. The ultrasonic waves travel through the oil and strikes the metallic shell of the transformer, providing the AE-150 with the signals needed to locate the problem.

Key Feature

The key feature of the AE-150 is the capability to synchronise acoustic emission signals with the electric partial discharge Signal. Powerful noise suppression is then achieved through averaging, increasing dramatically the probability of localisation.

  • 4 Acoustic Emission Sensors to detect PD (mounted on the main unit as an “X” shape, with flexible arms for transformer tank shape adjustment)
  • 1 Synchronisation Channel to filter out external random noise
  • 1 conventional PD measurement channel (HFCT)
  • Magnetically mounted on the transformer tank
  • Phase synchronisation using RF communication
  • Wireless communication with Portable Computer
  • Mirador Tx software with Auto-Loc: Automatic mode for easy diagnostic
  • Manual mode for advanced users
