Cutting Edge
Polescan is a non-destructive pole inspection system designed to evaluate the condition of wooden utility poles using ultrasound technology, where results are presented on a PDA to the inspector at the inspection site.
Proven Results
The Polescan system has been developed by IAMSL in New Zealand over the past ten years by a number of highly experienced Line Engineers and Software developers. The system has successfully been used on more than 100,000 wood poles throughout New Zealand, Australia and the Middle-East producing highly accurate results and increased workflow efficiencies for the companies involved.
The Scanner
The scanner is an ultrasonic test unit for use in making single pulse transmission time measurements in solid samples. The scanner consists of three units - a transmitter probe (red), a receiver probe (blue) and a display module (silver) that receives the readings in microseconds.
The unit operates by the transmitter probe sending an acoustic pulse through the tip of the probe and timing the subsequent interval until the pulse is successfully detected at the receiver probe. The transmission time will depend on the propagation within the sample and the thickness of
the sample.
Timber Probe Tool
The Polescan system also requires the user to determine any below groundline external decay. This is carried out by completing minor excavation to approximately 18 to 24 inches below the test level at groundline in three to four areas around the pole base. The timber probe tool then measures any external soft timber or decay. If any pole preservative or treatment is required, further excavation can proceed.
Benefits
The Polescan System delivers highly objective and dependable data on the condition of wooden utility poles, eliminating the current human reliance on subjective testing techniques. Polescan delivers fast, accurate and instantaneous results, allowing network managers to prioritize pole replacements and leave good poles in service.
