Polux

From Wikipedia, the free encyclopedia
Non destructive testing with Polux in Brazil

Polux is a measuring device for checking the condition of wooden electricity and telephone poles. This is a specific non-destructive testing tool for wooden poles.

Description

[edit]

Polux technology is used for safety and maintenance diagnostics. The measurements enable operators to climb poles safely and check the condition of the wood to estimate its remaining lifespan.[1][2][3][4]

History

[edit]
Security maintenance for men working on wooden poles lines.

The Polux technology was developed in the early 90s by Professor Jean-Luc Sandoz, following on from the Sylvatest, at the initial request of EDF, which had the dual problem of the safety and lifespan of their poles.[5] In 2003, the technology was presented at the 17th International Congress on Electrical Distribution Networks in Barcelona.[6] In 2017, a report by Orange's CGT insisted on the danger of unmaintained poles and demonstrated, through several large-scale comparative tests, the scientific contribution of Polux technology to increasing the safety of personnel climbing poles, drawing on the experience of Enedis.[7] It works with Picus software, which uses data consisting of local densitometry measurements at the ground line and hygroscopic measurements.[8][9][10] The Polux technology continues to be developed at the CBS-Lifteam Research and Development Centre in Switzerland.[11][12] The 5th version enables faster data collection and processing, with a miniaturised tool and the Picus application downloadable to smartphones.[13][14] Polux technology is used in a number of countries, including the United States, Canada, European Union, Africa and Asia.[15][16][17]

Awards

[edit]
  • In 2003, The Wall Street Journal awarded the first prize for innovation to Polux technology.[18]
  • In 2006, the 14th international symposium on non-destructive testing equipment presented advances in the technology.
  • In 2011, the International Seminar of Electrical Energy Distributors presented the use of Polux technology in Germany, using Deutsche Telekom as an example.[19]
