Underground cables provide a network of connecting power supply. However, as cables are buried underground, cable locating and fault finding is usually difficult.
Moreover, cable systems are exposed to a lot of risks, which may lead to dangerous consequences. For instance, if cable systems are damaged, people digging the ground for utilities or property construction may suffer electrocution. Similarly, underground cable faults may happen because of the flood, excavators, and various other activities.
In order to ensure uninterrupted and continuous power distribution, it is very important to detect underground cable faults in time and protect against cable faults.
Tips to Protect Cable Systems against Underground Cable Faults
Underground cable locating is the first and foremost challenge. Thereafter, it is possible to detect cable fault. The network of power cables under the ground includes switches, switchgear, and fuses housed together. The network of cables is contained in air insulated steel jars to prevent contaminants, wildlife, humans and other live parts from coming in contact. In addition, it reduced exposure to live parts.
The process of assembling cables is called pad-mounted gear. It can be supervised either remotely or manually.
Due to rising concerns over cable fault finding and locating, three common methods were coined to protect the cable system against major faults:
Tips to Protect Cable Systems from Physical Damage
Underground cables have proper infrastructure and withstanding capacity. These cable networks are not vulnerable to environmental hazards or challenges. They are designed with the ability to protect and prevent corrosion, water ingress, and certain mechanical damage as well.
However, in the event of extensive damage or challenging conditions, cables may suffer damage. Especially while digging trenches or executing property excavation work, there is a high risk of damage. Besides laying cable network deeper under the ground, some other precautionary measures should be taken to make sure it is safe. Different methods are used to provide protection to cables, which is highly influenced by the terrain, activity level, and voltage. Protection systems use various mechanisms such as:
The underground cable network is the most convenient power distribution system in the urban areas where overhead cables cannot be used. For continuous service and ensure, underground cable systems should be protected against damage and cable fault conditions. Only proper protection ensures uninterrupted service and reduces the risk of personal injury and accidents.

At any point of time, if you need to excavate or drill into the ground, there is risk of hitting utility pipelines and wires.
This may not only be extremely costly but can also be very dangerous if you happen to damage the underground pipes and cables. This is where you need utility location services to precisely locate the placement and depth of a utility system beneath.
What is a Utility Locator Service?
When you are preparing to excavate or dig, make sure you hire reliable utility locator service. Utility lines are not always there where they seem to exist.
Therefore, hiring an underground cable locator service is important. It not only helps to locate underground as well as hidden utilities, but you can also inspect how deep they are installed.
How do Utility Location Services help Determine Location of Buried Utilities?
For cable fault finding, utility location or pipe detection, technicians use Ground Penetrating Radar system and electromagnetic sensors that penetrate the surface non-invasively.
The signals generated by the device help locate underground pipes and cables, and allows the technician to create an accurate image or map of the exact location and depth of the utility system, no matter if it is buried.
With professional utility location services, you can have accurate information about underground utility lines without having to disrupt the existing structure.
State-of-the-art equipment can be used to find buried lines, conduits and voids, and also provides exact location of the same and depth. It is the ideal choice before you perform a digging or excavation project.
When should you hire Utility Locating Service?
The right time to hire utility location services is long before you start excavating or designing. Often, it is vital to detect the exact location and depth of utility lines during early stages of planning.
Having this crucial data will help to properly place the foundations, structures, trees, post support and other items. Moreover, it may be needed to relocate utilities. Utility locator companies help determine where the lines can be moved to minimise threat.
What are the Equipment Used for Utility Location?
Utility locator companies use electromagnetic cable and pipe locator equipment that allows the technicians to seamlessly adjust different cable and line conditions as well as detect unexpected soil conditions.
Such devices provide up to 97% accuracy and depth reading up to 13+ feet. Underground cable locator equipment is most beneficial in detecting utility cables and pipelines.
Utility location services are the best option to detect an underground utility line or cable. Modern electromagnetic equipment is used to identify the exact location and depth of each utility system. Make sure you hire an expert utility location company before you start with the project.
Digging up or drilling a concrete can be a laborious task, especially if you do not know what is in there. What if there is an obstruction beneath the concrete which may hinder the drilling or coring process? Do you precisely know which is the safe area to dig into? To find out what is in the concrete without digging it up, get the help of concrete X-ray or concrete scanning technique.
When excavating or drilling into asphalt or concrete, it is important to determine whether there is any potential obstruction such as utility lines, conduits, storage tanks or re-bar beneath the surface. After all, one cannot take the risk of breaking through an existing pipeline system tucked beneath a concrete. concrete X-ray in Melbourne, also referred to as concrete scanning, is a modern and innovative technology that uses GPRS system to inspect the subsurface of asphalt or concrete, and identify any dangerous element or potential obstructions.
The cutting-edge device harnesses electromagnetic ground penetrating radar technology, with the highest possible resolution, to easily locate what is beneath a concrete. It measures the electrical conductivity of different types of materials to determine what is located below a specific area of the asphalt or concrete. GPRS concrete X-ray provides reliable, safe and accurate Ground Penetrating Radar assessment before drilling or excavating. The technique is extremely functional and versatile in a large number of work conditions and environments, particularly for engineering, construction and industrial purposes.
Benefits of concrete X-Ray
There are numerous benefits of concrete x-ray Melbourne as highlighted below:
When it comes to technologies regarding underground services in Melbourne and Geelong areas, confusion between GPR — ground penetrating radar and X-Ray is bound to happen. Let us have a look at some of the basics of both of them.
GPR — Ground Penetrating Radar
GPR technology exploits safer radio waves as opposed to gamma rays used in concrete x-ray technology. One of the greatest things that differentiate GPR from x-ray technology is its capacity to give real time results. Underground services providers use ground penetrating radar precisely for this reason.
The term is very often misleading as many builders when they approach underground services provider use this to mean GPR. One of the reasons for the confusion is that this is an old technology which is accurately called cement or concrete radiography. Its main purpose is to identify any object underground by taking x-ray images of the layers.
While x-ray images are quite clear compared to GPR facts, it often consumes more time. Also, since it uses gamma rays, nearby places need to be evacuated before carrying out x-ray imaging.
Points of Comparison
(a) Concrete x-ray is confined to one section at a time
(b) Also, during x-ray scanning, nearby places need to be evacuated which causes loss of time
(c) Technologically, GPR allows the use of digital image even after the test. This makes processing and manipulation lot easier and less expensive
(d) Compared to GPR, concrete radiography requires more expensive training as well as equipments
What to use when
Though it is true that GPR is replacing concrete radiography quite faster, it depends on your requirement which technology is best suited to your projects.
Professional and experienced underground services providers in Melbourne and Geelong areas listen to your requirements carefully and then decide the best suitable technique.
These are some of the factors that play a major role in deciding which technique is best suited to your project.
Ponder over these factors, check with professionals if you are still not sure which of these should best suit you, and make an informed choice before you actually start your ambitious project.

The company is in the process of acquiring sophisticated software, novel scanning technology and capability to implement accurate data assessment. It is important to note that the company also conducts site survey and drafting making use of Auto CAD technology.
One area of interest is the method of how industrial metal detectors work. The most popular technology being used at present is called induction balance or Very Low Frequency. The VLF detector is made up of the transmitter and receiver coils. The first is an outer loop which covers a coil of wire. Electric power passes through this object in two directions (several thousands of times per second).The frequency of switching of direction every second creates the unit’s rate of recurrence.
The second is the receiver or inner coil loop with its interior wire functioning as antenna to pick up and magnify frequencies emanating from target objects beneath the ground. Electric current which passes through the transmitter produces an electromagnetic field. This is similar to that of the electric motor. The magnetic field’s polarity is at right angle against the coil. Every time current shifts direction, magnetic field polarity also changes. In other words, if the wire is parallel to the land, the magnetic field pushes down to the ground and pulls out of it. On the other hand, the fundamental method of detecting metal is through the Beat Frequency Oscillator or BFO.
GeoScan specialists have been trained to detect materials such as metal. Moreover, these technicians are well-versed in performing beneath-the-ground, obtaining evidence to be utilized for forensic research, archeological artifacts, and storage reservoirs buried under the earth’s surface.
