Precautions For High Voltage Installation
High voltage domestic electrical installation power lines are typically installed on utility poles, however, they can be submerged as well. Wherever you work it is essential to take the appropriate safety precautions when working with high-voltage electricity.
A shock from an electric source is the most dangerous. It can cause serious injury, or 3 Phase Meter Installation even death.
Insulation
Insulation is a crucial aspect of high voltage installations and must be maintained at the proper levels to protect against failure but also to avoid electric shocks. It acts as a barrier between the electrodes of a device and other parts of the circuit, making it difficult for anyone to get them directly, which can result in injury or even death.
Various materials are used to make insulation. The most popular was rubber material because it was easy to make and could stand up to the toughest conditions. Plastics have replaced rubber as the main material for high-voltage projects.
Some plastics are more durable than others, so you need to be aware of the characteristics of each insulation material when deciding on which is best for your project. You should be aware of the ways in which each material is able to resist, how durable it is and how flexible it is, and how it handles water, abrasion and other details.
These properties include thermal as well as chemical. These properties can help you choose the right material for your requirements.
When working with insulators in high-voltage environment, you must ensure that they are constructed of an material that is able to withstand the pressure and heat. Choose a material that can withstand temperatures up to 1000 degrees and humidity up to.
In addition it is essential to look for insulators that are resistant to fire and other dangers. This could be a material that is resistant to sunlight and ozone, and is also waterproof and impervious to chemical and oil.
It is also important to choose insulation that is designed to withstand the high tensions that are involved in power transmission. These insulators can be suspended insulation, strain insulators or shackle insulation.
They are often used to fill dead edges or sharp corners on power lines where a strong Tensile load is expected. Depending on the voltage of the line, these insulators are made of several glass or porcelain discs that are connected in series with metal links.
Sharp Points
Using a conductor that has sharp edges and points increases the chance of dielectric breakdown in the event a high voltage spike. Fortunately, most manufacturers are aware of this problem and have made a habit of employing heat-shrink tubing with 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 guideline to ensure a safe and successful installation is to hire a quality contractor. The most reliable contractors are well-versed of the dangers that come with high voltages and are able to implement a safety plan. This is the most difficult aspect of the process. It is essential that each member of the crew is aware of the job they are assigned and can use high-voltage terminology.
Dust
To ensure the safety of workers and avoid injuries, it is vital to ensure that dust does not enter a high voltage installation. This can be accomplished by using a dust tight construction. A protective cover for insulation is highly recommended.
High voltage equipment typically makes use of metal dust and insulation fibers. This is because they have similar characteristics of discharge and movement, and a small amount of dust can significantly reduce the breakdown voltage of an air gap.
However, the impact of these two impurities on breakdown behavior of an air gap is still unknown. To better understand the phenomenon of discharge of these materials, a series of experiments were conducted to examine their motion and discharge behaviors individually and together.
As illustrated in Figure 10, the voltage at which the particles lift of metal dust fluctuates as the size of the particles decreases, but the movement law is the same. When the voltage is below 7 kV, particles move mostly to the upper electrode. They bounce violently between electrodes when the voltage reaches 14 kV.
A series of tests with the help of a high-speed camera were conducted to observe the movement and discharge of these materials in detail. The results showed that metal dust and insulating fibre can be classified 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 was moving towards the electrodes. The area of movement created an area of dust columnar between them. The area had a low dust concentration.
The insulating fibers on the other hand were not moving when the voltage was low, but they began to lift when voltage increased. The resultant jumps between electrodes were quite fascinating.
During the test, the voltage was increased from -7 kV to 16 to -16 kV. Then the metal dust and insulating fibres started to move with a ferocious speed. The insulating fibres began bounce and lift up vigorously between the electrodes. This caused a sudden change in their movement. At the same time an enormous amount of dust particles were released from the discharge area which led to an explosion.
Voltage Breakdown
Breakdown is when an insulator undergoes an abrupt change in its electrical installation contractor properties. This is caused by a local electric field strength that is greater than the dielectric strength of the material. This could happen in air or any other type of insulator and could result in burns, shock or even fire.
Based on the material and shape of the object the shape and material of the object can lead to breakdown. Therefore, it is essential to test the materials that are used for high voltage installations.
For instance, the drain-to-source current determines the breakdown voltage of an electronic device such as a MOSFET. A technique known as gate-current extraction will determine the breakdown voltage.
Another method of measuring the breakdown voltage is to place a sample material between two electrodes and applying an extremely high voltage to it. The voltage is then increased until the material breaks down.
The material of an insulator, high voltage installation the distance between electrodes and the force of the electric field at the contact determine the voltage at which it breaks. This is a significant factor in determining the safe voltage that can be 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 used to measure changes in the insulator's ability to stand up to voltage.
Some conductors, such as copper and aluminum are more susceptible to breakdown than others. Aluminium can be subject to a breakdown voltage up to 3 kV/mm if it is exposed to dry air at normal atmospheric pressure. Aluminum cable is rated at a lower voltage than copper because of this.
Other insulators such as silicon may experience breakdown voltages as high as to 3.5kV/mm when exposed to dry atmospheric air at normal pressure. This is because silicon conducts better at a lower temperatures than aluminum.
Impurities, such as bubbles, can cause liquids' breakdown. They can cause a non-linear electric field strength between the electrodes which can increase the potential for breakdown.
It is a good idea to shield the conductive surfaces of devices with dielectric materials , such as glass or plastic. This can help to prevent the possibility of disintegrating and the risks associated with it.
High voltage domestic electrical installation power lines are typically installed on utility poles, however, they can be submerged as well. Wherever you work it is essential to take the appropriate safety precautions when working with high-voltage electricity.
