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.
