Enhance transmission distribution system reliability by rapidly locating PD with acoustic imaging

With the FLIR Si124, professionals can safely detect problems up to 100 metres away and analyse discharge patterns. The camera classifies three partial discharge types: surface discharge, floating discharge, and discharge into the air.

For many years, utility companies have been performing 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 an effective method utility organisations use to locate the existence of partial discharge (PD). It enables professionals to conduct more frequent predictive maintenance routines, helping to provide a crucial first warning of impending electrical failure that could lead to 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 acoustic image is overlaid onto a digital camera image with an easy-to-use, ergonomic, one-handed camera solution weighing slightly over 2 pounds (980 grams).

With the FLIR Si124, professionals can safely detect problems up to 100 metres away and analyse discharge patterns. The camera classifies three partial discharge types: surface discharge, floating discharge, and discharge into the air. Knowing the type and severity of the discharge allows users to prioritise repairs. Image captures are quickly uploaded over Wi-Fi to the FLIR Acoustic Camera Viewer cloud service so that the user can perform further in-depth analysis of the system-generated PD patterns. Users can then create reports and easily share them with colleagues. The Si124 enables customers to perform more frequent inspections, helping utilities keep the power following.
