Acoustic imaging, particularly through dedicated devices such as the AI865, is used to detect partial electrical discharges (PD). This process is critical for maintenance and monitoring of high-voltage equipment, as PD is a key indicator of insulation deterioration that can lead to equipment failure.

 

These devices take advantage of their ability to detect and locate sounds in the ultrasonic frequency range. PDs produce sounds in this range, which are often inaudible to the human ear, especially in noisy environments. An acoustic imaging device allows users to scan an area and visually see the location of ultrasonic sounds generated by PD on a digital image of the inspected components.

 

These devices offer several advantages for maintaining electrical systems:

- *Safety*: Technicians can visually locate PD points from a safe distance, reducing the risk of exposure to hazardous conditions.

- *Efficiency*: They enable users to quickly and accurately scan and pinpoint defective slots, reducing inspection times.

- *Ease of Use*: These devices are designed for easy operation, requiring little to no training. Users can turn on the device, select the frequency range and begin scanning.

 

The AI865 imagers are distinguished by their advanced features, such as the ability to detect and locate PD with a high degree of accuracy, even at distances of up to 130 meters. These devices are particularly useful in environments where access to electrical components is limited, such as in enclosed cabinets or high and hard-to-reach areas. They are also effective in generating detailed reports and analyzing PD, helping to improve maintenance management and prevent unplanned downtime
