What is a tracer wire used for in utility operations?

Tracer wire is specifically designed to assist in the detection and location of buried utilities. In utility operations, especially those involving underground installations, identifying the precise location of infrastructure like pipelines or cables is crucial. The tracer wire is typically laid alongside these utilities and is made of a conductive material. When a signal is sent through the wire, it can be detected above the ground with specialized equipment, enabling workers to accurately locate the underground utilities without the need for extensive digging or disruptive methods.

This functionality is essential for ensuring safety during excavation work, reducing the risk of accidentally damaging existing utilities. The other options do not align with the purpose of tracer wire: it does not enhance gas flow, measure gas pressure, or serve as a reinforcement for pipelines. Thus, the primary role of tracer wire in utility operations is to facilitate the identification and location of underground systems.
