Wood poles are widely used in Canada to support electric transmission and distribution lines. Since wood is a raw material, the material properties are affected by environmental conditions. Factors such as temperature, moisture, bacteria or fungi may induce the development of internal decay in the poles. Decayed areas could reduce the strength of a pole significantly, making it vulnerable to extreme weather conditions. In order to avoid sudden failures of wood poles, ensure the reliability of the electrical network and develop effective maintenance programs, Waterloo North Hydro needs to assess the internal condition of wood poles reliably.

在加拿大，木杆被广泛用于支撑输电和配电线路。由于木材是一种原材料，材料的性能受环境条件的影响。温度、湿度、细菌或真菌等因素可能导致两极内部腐烂。腐烂的区域会显著降低电线杆的强度，使其容易受到极端天气条件的影响。为了避免木电杆的突然失效，确保电网的可靠性，制定有效的维护方案，Waterloo North Hydro需要可靠地评估木电杆的内部状况。
