Overhead lines are key assets for power utilities such as Hydro-Québec, who is the industrial partner in this project. The replacement of line conductors of a specific line easily costs tens of millions of dollars, so it must be done only if really necessary. In that regard, the hardest part is to obtain accurate information about conductors' internal condition, especially regarding the presence of corrosion.The objective of this project is to develop a compact and lightweight multi-function probe to monitor the internal degradation conditions of aluminum cable steel reinforced (ACSR) conductors used for most of the overhead lines worldwide. From this information, one can estimate the residual lifetime of the line. The project therefore aims at filling the knowledge gaps required to succeed in the development of this probe. Demonstration of the effectiveness of the new probe will be realized in a laboratory environment (Laboratory of Experimentation, Research Institute of Hydro-Québec - IREQ). The results of the project will be transferred to the industrial partner as the projects runs.The project is based on strong background work realized by IREQ between 2011 and 2018 on the IREQ proprietary LineCore technology, used to measure the corrosion of the protective zinc coating, and on magnetic probes, used to measure the degradation of the steel core. The project also relies on numerous projects realized by Polytechnique Montreal in areas such as electromagnetic modeling and characterization of steel and metal properties with electromagnetic approaches. The project will involve the training of 2 Ph.D. students and 1 postdoctoral fellow, who will all become Highly Qualified Personnel (HQP) for the Non-Destructive Testing (NDT) industry, which is a very important sector of activity in Canada. The project will also generate substantial scientific knowledge.

架空线路是电力公司的关键资产，例如Hydro-Québec，该项目的工业合作伙伴。更换某一条线路的导线，动辄要花费数千万元，所以必须在真正有需要时才进行。在这方面，最困难的部分是获得有关导线内部状况的准确信息，特别是关于是否存在腐蚀的信息。本项目的目标是开发一种紧凑、轻便的多功能探头，用于监测世界上大多数架空线路所使用的钢芯铝绞线（ACSR）导线的内部退化状况。根据这些信息，可以估计线路的剩余寿命。因此，该项目旨在填补成功开发该探测器所需的知识空白。新探测器的有效性将在实验室环境中进行演示（魁北克水文研究所实验室）。该项目的成果将在项目运行期间转移给工业合作伙伴。该项目基于IREQ在2011年至2018年期间对IREQ专有的LineCore技术进行的强大背景工作，用于测量保护锌涂层的腐蚀，以及用于测量钢芯退化的磁性探头。该项目还依赖于蒙特利尔理工大学在电磁建模和电磁方法表征钢铁和金属特性等领域实现的众多项目。该项目将涉及2名博士的培训。学生和1名博士后研究员，谁都将成为高素质的人员（HQP）的无损检测（NDT）行业，这是一个非常重要的活动在加拿大的部门。该项目还将产生大量的科学知识。
