Different cable locators employ different methods to function. The two known methods, Passive Utility Detection locating naturally present or naturally produced signals known as a passive signal. The other is to locate a signal that is applied AKA an Active signal , [7] are called the Passive Utility Detection and Active Utility Detection.
The conventionally used aid in cable fault testing and location is the cable test van. The van is installed with conventional cable measuring systems for quickly reaching the location of any cable fault. In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.
The vapour-sensing tube leak detection method involves the installation of a tube along the entire length of the pipeline. This tube – in cable form – is highly permeable to the substances to be detected in the particular application. If a leak occurs, the substances to be measured come into contact with the tube in the form of vapour, gas ...
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...

In a distributed computing system, a failure detector is a computer application or a subsystem that is responsible for the detection of node failures or crashes. [1] Failure detectors were first introduced in 1996 by Chandra and Toueg in their book Unreliable Failure Detectors for Reliable Distributed Systems .
Detectable tape, here used to mark the location of a plastic pipe containing electrical wires. Detectable tape or Underground warning tape is a conductive tape typically applied over buried utilities made of non-conductive materials such as plastic, fiberglass, or cement.
In electric power distribution networks, a fault indicator is a device which provides visual or remote indication of a fault on the electric power system. Also called a faulted circuit indicator (FCI), [1] the device is used in electric power distribution networks as a means of automatically detecting and identifying faults to reduce outage time.
