FIELD TEST OF A NOVEL NON-DESTRUCTIVE TESTING DEVICE ON WOOD DISTRIBUTION POLES

Abstract


A field test was performed on 50 utility poles that had been removed from service. The poles were non-destructively tested with a novel device, the PoleXpert. The poles were then destructively tested. Results indicated that the device’s output correlated well with the actual bending strength of the poles. As such it appears that the device has potential to identify weak or structurally compromised poles. Seventeen (17) of the poles were reinstalled in the ground and tested. The remainder 33 poles were tested horizontally in a pole-testing fixture. The device demonstrated positive correlation in both situations.
