Precautions For High Voltage Installation

High voltage electrical power lines are usually mounted on utility poles but they can also be buried. No matter where you work it is important to take the proper precautions to take when working with high-voltage electricity.

An electric shock is the most hazardous. It can cause serious injury or even death.

Insulation

Insulation is an essential component of high-voltage installations and must be maintained at the proper levels to protect against failure, but also avoid electric shocks. Insulation acts as an insulator between electrodes and other circuit components which makes it impossible to directly touch them. This could cause injuries or even death.

Insulators can be constructed from a variety of materials. Rubber was the most well-known material due to its easy to create and could stand up to the toughest conditions. But, now, plastics have replaced it as the preferred material for most high-voltage applications.

Certain plastics are more resilient than others. You should carefully consider the properties of each material prior to deciding which is the best for your project. It is important to be aware of the ways in which each material will resist, how tough it can be and how flexible and how it deals with water, abrasion, and other elements.

The properties of thermal and chemical properties are also crucial. Knowing the resistance to acid and alkalis, the ability to withstand extreme temperatures and the way it absorbs water are all factors that will help you determine which material is suitable for your needs.

When working with insulators in high-voltage environment, it is important to ensure that they're made of something that can stand up to the pressure and heat. This means that you need to choose a material that can stand up to temperatures of at minimum 1000 degrees and is resistant to humidity.

In addition to this it is important to look for insulation that is resistant to fire and other hazards. This could include an item that is water-proof as well as resistant to chemicals and Electrical Installation Service oil or even a material capable of defending against sunlight and ozone.

It is essential to search for insulators that can stand up to the extreme tensions that are associated with power transmission. These could be suspension insulators or shackle-insulators, or strain insulators.

These insulators are utilized to cover dead edges or sharp corners on power lines where a strong Tensile load is expected. Based on the line's voltage, these insulators could be made up of a number of porcelain or glass discs that are connected in series with metal links.

Sharp Points

Conductors with sharp edges or points increases the risk of dielectric breakage in the event a high voltage spike. The majority of manufacturers have realized this and have made it a point to make use of heat-shrink tubing that has adequate dielectric strength. A well-designed system will take steps to mitigate the risks of a poorly cut insulation, which is a common issue for high-voltage installers.

It is a good idea to hire a qualified contractor to ensure a successful and safe installation. The most reliable contractors have a robust safety program in place and are aware of the dangers associated with high voltages. The most difficult part of this procedure is ensuring that every employee is aware of their job and is aware of the jargon used in high-voltage installations.

Dust

In order to ensure the safety of personnel and avoid injury, it is important to ensure that dust doesn't get into a high voltage installation. Dust-proof constructions are a good option. It is also recommended that a protective cover be applied to the insulation.

High voltage equipment often makes use of metal dust and insulation fibers. This is because they have similar characteristics in discharge and movement and a small amount dust can greatly reduce the breakdown voltage of an air gap.

It is unclear what effect these impurities have on the behaviour of the breakdown of an air gap. To better understand the phenomenon of discharge of these materials, a series of tests were conducted to investigate their discharge behavior and motion both separately and together.

Figure 10 shows that the lifting voltage for dust particles in the form of metal changes in proportion to the size of the particles however the motion law remains the same. When the voltage is below 7 kV, the particles move mainly to the upper electrode. They bounce violently between electrodes when they reach 14 kV.

A series of tests with cameras that can move at high speeds were conducted to study the movement and discharge of these materials in detail. The results showed that metal dust and insulating fibres could be divided into three states: close-and-contact sate (or distant sate), distant sate (or jump sate).

The dust of metal that was in contact with sate moved towards the electrodes. Its movement area created an area of columnar dust between them. The concentration of the dust in this area was relatively low.

The insulating fibers, on the other hand did not move when voltage was low, but started to rise when voltage increased. The resulting jumps between the electrodes were fascinating.

During the test, the voltage increased from -7 kV, to -16 kV. Then, the metal dust and insulating fibres began to move rapidly. As the insulating fibres ascended and bounced, they shook violently between the electrodes, causing an abrupt change in motion. At the same moment the large amount of dust particles were ejected from the discharge zone which caused an explosion.

Voltage Breakdown

Breakdown is when an insulator undergoes rapid changes in its electrical installations and maintenance installation service (Full Write-up) properties. This is caused by a local electric field strength that exceeds the dielectric strength of the material. This can happen in air or any other insulator and could cause fire, burns or shock, or explosions.

Depending on the material and shape of the object, different voltages could cause breakdown. This is the reason why testing the materials used in high voltage installation is vital.

For instance, the drain-to-source current determines the breakdown voltage of a semiconductor device like a MOSFET. A technique known as gate-current extraction can determine the value.

Another method of measuring the breakdown voltage is to put a sample material between two electrodes and applying an intense voltage to it. The voltage is then increased until the material has broken down.

The material of an insulator as well as the distance between electrodes and the strength of the electric field that is present at the contact determine the voltage at which it breaks. This is a crucial factor in determining how much voltage can be safely applied to an insulation.

Engineers can utilize dielectric breakdown tests to determine the maximum voltage their designs are able to handle. It can also be utilized to observe any changes in the ability of the insulation to resist the voltage.

Copper and aluminum are more susceptible to deterioration than other. Aluminum can experience breakdown voltages of up to 3 kV/mm if it is exposed to dry air at a normal atmospheric pressure. Aluminum cable is rated at a lower voltage than copper due to this.

Other insulators like silicon can be subject to breakdown voltages of up to 3 phase meter installation.5kV/mm when they are exposed to dry atmospheric air at normal pressure. This is due to the fact that silicon conducts at lower temperatures than aluminum.

Impurities, such as bubbles, can cause liquids to breakdown. This can result in an electric field that is non-linear between the electrodes that can increase the breakdown potential.

It is recommended to insulate the conductive surfaces of devices with dielectric materials , such as glass or plastic. This can help safeguard against the possibility of breaking and the resulting dangers that come with it.
