What are the two classifications of underground fault locating equipment?

The correct classification of underground fault locating equipment includes terminal and tracer devices. Terminal equipment is used to establish the connection point and often provides the means to connect to the system where the fault is suspected. Tracer equipment, on the other hand, is specifically designed to follow the path of utility lines and can help pinpoint the location of faults by sending signals along the lines. This two-part approach is critical in underground fault locating because it allows for accurate identification and isolation of faults to ensure maintenance and repair tasks can be conducted effectively.

The other classifications do not accurately represent the standard terminology and functions commonly used in underground fault locating. For example, scanning and detecting equipment may refer to general types of diagnostic tools but lacks the specificity needed to classify the equipment used for underground fault finding. Similarly, probe and chart options tend to relate more to measurement and recording rather than active locating of faults in underground settings. Signal and receiver solutions might be components of a fault locating system but do not encapsulate the complete functionality as efficiently as terminal and tracer terminology does. Thus, understanding the role of both terminal and tracer devices is essential for effective fault locating in underground systems.
