What is a common method of detecting cable leak locations?

Using intermittent tone generators to detect cable leak locations is common because this method allows technicians to send a specific tone through the cable. When there is a leak, the signal can escape, altering the expected tone at the receiving end, which helps in pinpointing the location of the leak. This technique is effective because it provides a clear indication of where issues may exist, and the audible differences can guide the technician to investigate further.

Visual inspections and listening for audio signals have their merits but are often less precise. Visual inspections might miss subtle signs of a leak, while simply listening may not provide enough information to accurately locate the source. Conducting thermal imaging is useful for identifying hotspots or overheating issues but does not directly relate to detecting cable leaks specifically. Therefore, using intermittent tone generators stands out as a reliable and targeted approach to identifying cable leak locations.
