Cable fault locator manufacturers How to locate the cable fault locator? As the number of buried and hidden utility lines continues to increase, how to route them becomes an even greater challenge. Electricity, natural gas, sewer and telecommunication lines make us how to locate the cable fault locator manufacturer? As the number of buried and hidden utility lines continues to increase, how to route them becomes an even greater challenge. Electricity, gas, sewer and telecommunications lines clutter the ground beneath our feet and criss-cross the walls of most buildings.

Finding and identifying these lines is a critical step before building or maintaining a project to keep your crew safe while reducing potentially costly mistakes. Wire tracers and cable fault locating instruments are specially designed to help you locate live or de-energized wires, cables and pipes, whether underground or hidden in walls. Cable fault locators are also called cable fault testers. Wire tracers/cable locators cannot detect metal objects like magnetic detectors.

Instead, they rely on the target having a charge or signal placed on it, which is detected by a receiver within the locator. Many utilities emit an electrical charge or transmit a signal when the line is energized. In many cases, each line has a different signal, making it easy to distinguish the different lines.

In the case of unmarked lines, many wire tracers can use a transmitter to sense a signal onto the line in order to find the signal. Typically, the target must be metallic to conduct the signal, although a radiosonde or microtransmitter can also be used with plastic tubing. To sense a signal onto a pipe or cable, signal clips or clips are often used to connect the transmitter directly to the line or pipe to be located.

The signal will then travel down the pipe or cable. In areas where wiring is not accessible, the transmitter can also sense the signal from the ground, across the ground to the utility. Wire tracers/cable locators are usually available in single or multi-frequency units.

Each unit has its advantages and limitations. A single frequency cable fault location instrument consists of a transmitter that emits a single high frequency signal. The signal is picked up by underground lines and radiated back to the receiver.

Single-frequency systems work well on lines and pipes in uncrowded areas, because high frequencies have a tendency to absorb everything underground, creating a distorted signal and making it difficult to distinguish between power, gas, or communication lines. Another limitation is that single frequency locators cannot determine the depth of the line. Multi-frequency cable fault locating instruments allow users to tune the transmitter frequency to the material of construction of the pipeline or pipe they are locating.

Iron, copper, and aluminum each respond better to different frequencies, making multi-frequency locators better at distinguishing between individual lines. Multiple frequencies also make a wider range of tasks easier, as higher frequencies are better for picking up more signals, while lower frequencies are easier to follow a specific line. Most multi-frequency locators can also estimate the depth of a pipeline or pipe.

Some cable locators include a current measurement indicator that measures the current flowing to the line, helping to differentiate the line and ensuring the user stays on the original line……Especially suitable for crowded areas where lines cross each other. Using a Cable Fault Locator Instrument There are a variety of cable locators to choose from depending on the application. Some are designed for use with underground lines and pipes, while others are better suited for tight areas of walls (wire tracers).

As mentioned above, a cable locator usually consists of a transmitter (to sense the signal) and a receiver (to read the signal that is transmitted from the line returning from the transmitter). Matching a locator to a specific application is the first step in using a locator properly. There are two main methods of using wire tracers/cable locators for pipe and pipe cleaning.

Active locating involves searching for specific lines by using direct connections or through inductive signals. The locator is connected directly to the line, or, if direct connection is not possible, the frequency is selected and sensed to the ground and radiated by the utility. Active location refers to a situation where a specific line or pipe must be placed for maintenance or repair.

Passive localization involves scanning an area for unknown lines. Users simply scan the area with the receiver to find tools that radiate or re-radiate frequencies. Passive positioning does not allow the operator to distinguish the type of line, but is very effective for ensuring that there are no hazardous areas before digging.

Ground conditions can have a significant impact on the signal when using a cable locator to locate underground lines and pipes. Clay and moist soil are very conductive and help provide a stronger signal with less interference. On the other hand, dry soil is a poor conductor, which makes it more difficult for the signal to travel down the line or pipe, increasing the potential for distortion or interference.

Sometimes simply adding water to the ground near the transmitter is enough to improve signal strength.
