When looking at subterranean utilities, the Cable Avoidance Tool (CAT) and Signal Generator (Genny) emerge as instrumental aides in navigating the concealed networks below our feet. However, like all tools, they possess certain limitations. The main areas where a CAT and Genny might falter include detecting utilities beyond a certain depth, locating inactive or non-conductive utilities, and identifying certain types of materials.
Depth Limitations
The proficiency of CAT and Genny in detecting underground utilities is bound by depth. Particularly, the detection capabilities may taper off beyond a certain depth, which could vary based on the specific model and prevailing ground conditions. For instance, if a utility line is laid deeper than the detection range of the tools, it remains veiled from the detection sweep, potentially leading to hazardous encounters during excavation activities.
Active vs. Inactive Utilities
CAT and Genny are adept at picking up signals from live power cables, owing to the flow of electricity which renders these utilities detectable. However, during instances where the power is turned off, or in the case of utilities that do not carry a live electrical charge, the detection becomes challenging. The scenario of streetlights during daylight hours stands as a classic example, where the absence of an electrical flow renders them undetectable.
Conductive vs. Non-Conductive Materials
The material composition of the utility lines plays a pivotal role in their detectability. While metallic conduits can be traced owing to their conductive nature, non-conductive materials such as plastic pose a challenge. For instance, plastic water or gas pipes remain elusive to the detection capabilities of CAT and Genny, necessitating alternative methods or tools for accurate location and avoidance.
