Precautions For High Voltage Installation
High voltage electrical power lines are often placed on utility poles, but they may also be buried. Wherever you work it is important to take the appropriate precautions to be aware of when working with high-voltage electricity.
The biggest danger is an electric shock. It can cause serious injuries, or even death.
Insulation
Insulation is a crucial component of high voltage installations. It is essential to keep it at the proper levels to prevent failure and electric shocks. Insulation acts as an obstruction between electrodes as well as other circuit parts, making it impossible to get them in contact with one another. This could cause injuries or even death.
Insulators can be made from a variety of materials. Traditionally, rubber was a preferred choice because it was easy to make and was able to withstand the most extreme conditions. However, today, plastics have replaced it as the material of choice in the majority of high-voltage installations.
Certain plastics are more resilient than others, and you should be aware of the characteristics of each insulation material when deciding which is the best for your project. It is important to be aware of the ways in which each material will resist, how durable it is, how flexible it is and how it handles water, abrasion and other details.
Chemical and thermal properties are also crucial. Knowing the resistance to alkalis and acid as well as the capacity to withstand extreme temperatures, and the way it absorbs moisture are all things that can help you decide which material is best for your needs.
You must ensure that Insulators are resistant to heat and pressure when used in high-voltage environments. This means you must choose a material which can stand up to temperatures of at minimum 1000 degrees, and is resistant to humidity.
You should also look for insulators which are resistant to fire and other dangers. This could include a material that is water-proof as well as resistant to chemicals and installation Electrician oil or even a material capable of defending against sunlight and the ozone.
It is essential to look for insulators that can withstand the extreme tensions that are associated with power transmission. These could be suspension insulators, shackle insulators or strain insulators.
These insulators are used for dead ends or sharp corners on power lines where a strong tensile load is expected. Based on the line's voltage, these insulators are made of several glass or porcelain discs, which are joined in series with metal links.
Sharp Points
Conductors with sharp edges or sharp points increase the chance of dielectric breakdown in high voltage spikes. The majority of manufacturers have realized this and made it a priority to use heat-shrink tubing that has adequate dielectric strength. A well-designed system will also take steps to reduce the risk of improperly trimmed insulation which is a common cause of accidents for the experienced high voltage installer.
A good rule of thumb to ensure a safe, efficient Installation Electrician is to employ a quality contractor. The best contractors have a well-constructed safety program in place and are well educated about avoiding the hazards that come with high voltages. This is the most challenging part of the procedure. It is important that each employee of the team understands their role and can use high-voltage terminology.
Dust
In order to ensure the safety of employees and avoid injuries, it is essential to ensure that dust doesn't infiltrate a high voltage system. Dust tight constructions are a great option. It is also recommended that a protective cover should be placed on the insulation.
High voltage equipment usually employs metal dust and insulation fibers. This is due to their similar movement and discharge characteristics, and a small amount dust can dramatically reduce the breakdown voltage of an air gap.
However, the impact of these two impurities on breakdown of an air gap is still an unknown. A series of tests were conducted to better know the motion and discharge behavior of these materials.
Figure 10 shows that the lifting voltage for dust particles in the form of metal changes with decreasing particle sizes however, the motion law is the same. The particles are mostly moved towards the electrode on the upper side when the voltage is less than -7 kV, and they bounce violently between electrodes once they reach 14 kV.
To observe the movement and discharge of these two materials with a greater depth, a series of tests were carried out with cameras that operate at high speeds. The results showed that metal dust and insulating fibres could be classified into three different states: close-and-contact sate (or distant sate), distant sate (or jump sate).
The metal dust that was in contact with sate was moved towards the electrodes. The area of movement created an area of columnar dust between them. The concentration of dust in this area was low.
The insulating fibers in contrast were not moved when voltage was low, but began to rise as voltage increased. The resultant jumps between electrodes were extremely interesting.
During the test, the voltage was increased from -7 kV to 16 KV. Then, the metal dust and insulating fibres began to move rapidly. When the insulating fibres rose and bounced, they shook violently between the electrodes and made a sudden change of their motion. A lot of dust particles also expelled from this area and caused an explosion.
Voltage Breakdown
Breakdown is when an insulator undergoes an immediate change in its industrial electrical installation properties. This is due to the local electric field strength that is greater than the dielectric strength of the material. This can happen in air or any other type of insulator and may cause shock, burns or even fire.
Depending on the material and shape of the object, the shape and material of the object can lead to breakdown. This is why testing the materials used in high voltage installation is crucial.
For example, the drain-to-source current determines the breakdown voltage for devices made of semiconductors, like a MOSFET. A technique known as gate-current extraction can be used to determine the breakdown voltage.
Another method to determine the breakdown voltage is to put a sample of material between two electrodes, and then apply a high voltage. This voltage is then increased until the material has broken down.
The breakdown voltage of an insulator is dependent on the material used, the distance between the electrodes, as well as the electric field strength at the contact. This is an important aspect in determining the safe voltage that can be applied to an insulator.
Engineers can utilize dielectric breakdown tests to determine the maximum voltage their designs are able to handle. It can also be used to monitor changes in the insulator's ability to stand up to voltage.
Aluminum and copper are more susceptible to deterioration than other. Aluminum can suffer breakdown voltages of up to 3 phase meter installation kV/mm when exposed to dry air at a normal atmospheric pressure. This is the reason that aluminum cable is rated to a much lower voltage than copper.
Other insulators, like silicon, can experience breakdown voltages of up 3.5 kV/mm when exposed to dry atmospheric air at normal pressure. This is because silicon conducts at lower temperatures than aluminum.
Impurities, such as bubbles, can cause liquids to break down. This can result in an electric field strength that is not linear between the electrodes which can increase the breakdown potential.
It is generally a good idea to shield the conductive surfaces of a device by dielectric materials such as glass or plastic. This can help to protect against the possibility of failure and the subsequent hazards associated with it.
High voltage electrical power lines are often placed on utility poles, but they may also be buried. Wherever you work it is important to take the appropriate precautions to be aware of when working with high-voltage electricity.
