Quick identification of partial discharge (PD) with Acoustic Imaging

The FLIR S-124 industrial acoustic imaging cameras are designed to identify partial discharge areas quickly and to increase the reliability of transmission and distribution systems.

The customer’s challenge
For years, utility companies have performed partial discharge (PD) measurements on high-voltage electric equipment. PD is an indicator of insulation deterioration that can lead to equipment failures or, even worse, a catastrophic incident. With traditional ultrasonic solutions, the systems can be large and cumbersome, and the inspection reports usually need to be analysed by an acoustic engineer. Given this, inspections can become less frequent, leaving equipment like motors, generators, switchgear, and transformers vulnerable to PD-related issues.

Highlighted Solution
Acoustic imaging, or the ability to see ultrasonic sound, has emerged as effective method organisations use to locate the existence of partial discharge (PD). It enables professionals to conduct more frequent predictive maintenance routines, helping provide a crucial first warning of impending electrical failure that could lead to the downtime of critical systems. The FLIR Si124 industrial acoustic imaging camera senses, displays, and records sound waves, producing a precise acoustic image. In real-time, the auditory image is overlaid onto a digital camera image, all with an easy-to-use, ergonomic, one-handed camera solution weighing a little more than 2 pounds (980 grams).
With the FLIR Si124, professionals can safely detect problems up to 100 meters away and analyse discharge patterns. The camera classifies three types of partial discharges: surface discharge, floating discharge, and discharge into the air. Knowing the type and severity of the discharge allows the users to prioritise repairs.

The Si124 enables customers to perform more frequent inspections, helping utilities keep the power flowing. Image captures are quickly uploaded over Wi-Fi to the FLIR Acoustic Camera Viewer cloud service for the user to further analyse the system-generated PD patterns. Users can then create reports and easily share them with colleagues.
