Onsite Infrared Thermography & Ultrasound Scanning

Usually, before an electrical component burns up it will heat up. Burned electrical components will cause serious damage to the system. An early detection is crucial in proceeding for the next necessary step to ensure system’s safety. 

The options for early detection includes Infrared thermal. This device is used to detect abnormalities in the system (i.e. hot spots and other defects) and used to perform inspections on electrical equipment as excess heat is usually the first sign of trouble on electrical apparatus.

Fortunately, PQE provide the service and below are the list of assets that we can inspect:

  • Electrical Switchgear

  • Transformer

  • Distribution Board

  • Motor

  • Generator

Another service provided by PQE is the Ultrasound scanning. It is used to detect Partial discharge, arcing and corona all produce ionization which disturbs the surrounding air molecules. An Ultraprobe detects high frequency sounds produced by these emissions and translates them (via heterodyning) down into the audible ranges. The specific sound quality of each type of emission is heard in headphones while the intensity of the signal is observed on a display panel. These sounds can be recorded and analyzed through ultrasound spectrum analysis software for diagnosis & reporting.

Normally, electrical equipment should be silent, although some equipment such as transformers may produce a constant 50 cycle hum, or some steady mechanical noises. These should not be confused with the erratic, sizzling frying, uneven and popping sound of an electrical discharge.

Using the ultrasound inspection can be performed at all voltage levels (low, medium and high) and is used to detect:

  • Corona

  • Partial discharge or tracking

  • Arcing

  • Mechanical vibrations (transformers)
