Precautions For High Voltage Installation
High voltage electrical power lines are often placed on utility poles, but they can be submerged as well. Whatever the location you work in, it is important to know the proper procedures for working with high voltage electricity.
The biggest danger is an electric shock. This could cause serious injuries or even death.
Insulation
Insulation is a crucial component of high voltage installations. It must be maintained at the appropriate levels to prevent any failure or electric shocks. It acts as a shield between the electrodes of a device and other components of the circuit, making it difficult for anyone to get them directly, which can lead to injury or death.
Different materials are used to create insulators. Rubber was the most sought-after material due to its simplicity to make and could withstand the harshest conditions. Plastics have replaced rubber as the main material for high-voltage projects.
Certain plastics are more resilient than others. You must carefully consider the properties of each insulation material prior to deciding which is best suited to your project. It is important to know what each material is able to resist, the strength it can offer and how flexible, and how it handles water, abrasion, and High Voltage Installation other facets.
Chemical and thermal properties are also important. These properties will assist you in selecting the ideal material for your requirements.
When working with insulators in a high voltage environment, you need to be sure that they are made from materials that can withstand the heat and pressure. You should choose an item that can withstand temperatures of up to 1000 degrees as well as humidity.
It is also important to look for insulators that are resistant to fire and other dangers. This could be a material that can resist sunlight and ozone, is waterproof, and resistant to chemical and oil.
It is also important to select insulations that are made to withstand the rigors of tension associated with power transmission. They could be suspension insulators, shackle insulators or strain insulators.
These insulators can be used to protect power lines from sharp corners or dead ends. Depending on the line's voltage, the insulators may consist of several glass or porcelain discs, which are joined in series by metal links.
Sharp Points
Conductors with sharp edges or points increase the chance of dielectric breakdown in high voltage spikes. Fortunately, the majority of manufacturers are wise to this problem and high voltage installation have made a point of using heat-shrink tubing with a suitable dielectric strength. A well-designed system can take steps to mitigate the risks of insulation that is not properly cut, which is a typical issue for high-voltage installers.
A good rule of thumb to ensure a safe, efficient installation is to employ a reputable contractor. The most reliable contractors have a strong safety program in place and are trained to avoid the dangers that come with high voltages. The most challenging part of this process is to ensure that every employee is aware of his or her job and is aware of the terminology used by high voltage companies.
Dust
In order to protect personnel and avoid injury, it is important to ensure that dust does not enter a high voltage installation. Dust-proof constructions are a good choice. A protection cover for insulation is recommended.
Metal dust and insulating fibers are often combined in high voltage equipment. This is because they have similar discharge and movement characteristics, and a small amount dust can dramatically reduce the breakdown voltage of an air gap.
However, the effect of these two impurities on breakdown of an air gap is still a mystery. A series of tests were conducted to know the discharge and motion behavior of these materials.
Figure 10 illustrates that the voltage of lifting for metal dust varies with decreasing particle sizes however, the movement law is the same. The particles are moved mainly to the upper electrode when the voltage is lower than 7 kV, and then they bounce violently between electrodes when the voltage is the voltage of -14 kV.
In order to observe the movement and discharge of these two materials in greater detail A series of tests were carried out using an ultra-fast camera. The results show that the movement of metal dust and the insulating fibre can be separated into three states: close and contact Sate, distant sate and jump sate.
When the dust of metal was present in contact sate, it moved towards the upper electrode . the area of movement resulted in a specific columnar dust area between the electrodes. This area had a relatively low dust concentration.
The insulating fibers however were not moved when voltage was low but began to rise when the voltage increased. The voltage jumps between electrodes were fascinating.
During the test, voltage was increased from 7 kV to 16 kV. The metal dust and insulating fibers began to move quickly. The insulating fibres began move and bounce violently between the electrodes. This caused an abrupt change in their motion. A large number of dust particles were also released from the area and caused an explosion.
Voltage Breakdown
If an insulator undergoes a rapid change in its electrical installation and maintenance properties, it is called breakdown. This is caused by a local electric field strength that is higher than the dielectric strength of the material. This can occur in air or any other insulator and may lead to fire, burns, or explosions.
Depending on the material and the shape of the object, breakdown can occur at different voltages. This is why testing of the materials used in high voltage installations is vital.
For instance the breakdown voltage of a semiconductor device such as a MOSFET is determined by its drain-to-source current. A technique known as gate-current extraction will determine the breakdown voltage.
Another method of measuring the breakdown voltage is to put the material in question between two electrodes and applying the material to a high voltage. The voltage is then increased until it breaks down.
The breakdown voltage of an insulator is based on its material, Electrical Installation domestic the distance between the electrodes, as well as the electric field strength at the contact. This is a crucial factor in determining the safe voltage that can be applied to an insulation.
Engineers can utilize dielectric breakdown testing to determine the maximum voltage their designs are able to withstand. It is also used to track changes in the insulator's capacity to resist voltage.
Certain conductors, including aluminum and copper are more susceptible to break than other. Aluminum can suffer an energy loss of up to 3 kV/mm if it is exposed to dry air at normal atmospheric pressure. The aluminum cable is rated to less voltage than copper because of this.
Other insulators, like silicon, can experience breakdown voltages of up 3.5 KV/mm when exposed dry atmospheric air at normal pressure. This is because silicon conducts at lower temperatures than aluminum.
Impurities, such as bubbles, can cause liquids to degrade. They can create an electrical installation and maintenance field with a non-linear strength in the space between electrodes, which can increase the potential for breakdown.
In this regard, it is usually a good idea to protect the conductive surfaces of a device using dielectric materials such as glass or plastic. This will protect you from the possibility of breaking down and the dangers that come with it.
