  • Evaluation of Non-Destructive Testing (NDT) Methods for Wood Power Poles

    Abstract: This technical report aims to test the effectiveness of several non-destructive testing (NDT) technologies on wood utility poles to detect deterioration. The project will assess commercially available devices using sound velocity and drilling resistance methods for in-field measurements. The goal is to extend the lifetime of wood poles, prevent unexpected failure, and enhance their in-service life beyond the current 75-year expectation. Despite the benefits of wood poles, it is difficult to obtain reliable deterioration metrics on in-service poles, which can lead to premature decommissioning or pole failure. NDT methods have been developed to replace labor-intensive methods, but none have been largely adopted in common practice. Therefore, creating a database of validated data would expedite adoption. Integrating precise and efficient wood utility pole NDT can increase installation energy resiliency and facility sustainment in a fiscally responsible way, ensuring high standards of delivery of services.
