Question: We have under ground conduit that has been been hit with a drill bit. Not enough to trip cb. What is the best way to find the affected conduit when you have multible conduits UG. Can not shut down to megg cables. Cable was hit and caused ittle interruption did not trip cb.

Method 1: Thermal Imaging Use a thermal imaging camera to scan the ground along the conduit path. The affected conduit will emit more heat due to the damage.

Method 2: Electromagnetic Field Detection Deploy an electromagnetic field (EMF) detector along the conduit path. The damaged conduit will create an abnormal EMF pattern.

Method 3: Pipe and Cable Locator Use a pipe and cable locator to trace the conduits and identify the one that has been damaged. The locator will emit a signal that can be detected by a receiver.

Method 4: Conduit Inspection Camera Insert a conduit inspection camera into the conduits to visually inspect for damage. Look for any breaks, cracks, or other signs of impact.

Method 5: Access Point Cameras If there are access points along the conduit path, insert a camera to take pictures or videos of the interior. This can help identify the exact location of the damage.

Additional Tips: If possible, locate the approximate area of the damage based on the drill bit entry point. Use non-destructive methods whenever possible. Exercise caution when working with energized cables. If the damage is extensive, consider contacting a qualified electrician or utility company for assistance. Flag for review
