Precautions For High Voltage Installation
High voltage electrical installations testing power lines can be set up on utility poles. They can also be buried. Whatever the location you work in it is crucial to be aware of the appropriate procedures for working with high voltage electricity.
An electric shock is the most hazardous. This could result in serious injury or even death.
Insulation
Insulation is an essential part of high voltage installations electrical. It must be maintained at the correct levels to prevent failure and electric shocks. It acts as a barrier between the electrodes of a device and the rest of the circuit, making it impossible for someone to touch them directly, which could result in injury or even death.
Various materials are used to create insulators. Historically, rubber was the most popular material because it was simple to manufacture and worked well under the most extreme conditions. However, plastics have now replaced it as the preferred material in most high-voltage applications.
Certain plastics are more resilient than others, and you must look at the properties of every insulation material when deciding which is best for your project. Specifically, you need to know the strength of each, High Voltage Installation the toughness it is, its flexibility and how it handles moisture and abrasion.
Chemical and thermal properties are also important. 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 the right material for your specific needs.
When working with insulators in a high voltage setting, you should ensure that they are made from something that can stand up to the pressure and heat. Choose one that is able to stand up to temperatures of up to 1000 degrees as well as humidity.
Additionally it is important to look for insulators that are resistant to fires and other dangers. This might include a material that is resistant to sunlight and ozone, is water-proof and impervious to chemical and oil.
It is also essential to choose insulation that is designed to withstand the extreme tensions caused by power transmission. These could be suspension insulation as well as shackle insulators, strain insulators.
These insulators are used for dead edges or sharp corners on power lines in which a heavy tensile load is expected. Depending on the line's voltage the insulators may consist of several glass or porcelain discs, which are joined to each other by metal links.
Sharp Points
Conductors with sharp edges or sharp points increase the possibility of dielectric breakdown in high voltage spikes. Fortunately, many manufacturers are wise to this problem and have made a habit of using heat-shrink tubing containing the right dielectric strength. A properly designed system will take steps to reduce the dangers of poorly trimmed insulation, which is a common issue for high-voltage installers.
A best practice to ensure a safe, efficient installation is to employ a quality contractor. The most reliable contractors have a well-constructed safety program in place and are educated about avoiding the hazards that come with high voltages. This is the most challenging aspect of the procedure. It is crucial that every member of the crew understands their job and is able to use the terms high-voltage.
Dust
To ensure the safety of employees and prevent injury, it is important to ensure that dust doesn't get into a high voltage installation. Dust-proof constructions are a good choice. A protective cover for insulation is advised.
High voltage equipment often employs metal dust and insulation fibers. This is due to their similar discharge and movement characteristics, and a small amount dust can drastically reduce the breakdown voltage of an air gap.
It is not yet clear what effect these impurities have on the behaviour of an air gap's breakdown. A series of experiments was conducted to better understand the discharge and motion behavior of these materials.
As illustrated in Figure 10, the lifting voltage of dust particles varies as the size of the particles decreases, however, the movement law remains unchanged. The particles are moved mainly towards the upper electrode when the voltage is lower than 7 kV, and then they bounce violently between electrodes when they reach the voltage of -14 kV.
A series of tests with cameras that can move at high speeds were conducted to observe the movement and discharge of these materials in greater detail. The results show that the movement of metal dust and the fibers that insulate can be separated into three states: close contact the sate state, distant sate and jump sate.
The metal dust that came in contact with sate was moved towards the electrodes. The area of movement created an area of dust columnar between them. This area had a low concentration of dust.
The insulating fibers however, didn't move when voltage was low, but began to rise as the voltage increased. The voltage jumps between electrodes were quite interesting.
During the test, the voltage was increased from -7 kV, to -16 in kV. The metal dust and the insulating fibers began to move quickly. The insulating fibres began to bounce and lift off vigorously between the electrodes. This caused a sudden change in their motion. A lot of dust particles also ejected from this area, which caused an explosion.
Voltage Breakdown
Breakdown occurs when an insulator goes through an abrupt change in its electrical properties. This is due to an electric field strength local to the material that exceeds the dielectric strength of the material. This can occur in air or any other insulator and may lead to fire, burns, shock or even explosions.
Based on the material used and the shape of an object, breakdown can occur at different voltages. This is why testing the materials used in high voltage installation is essential.
For instance, the breakdown voltage of a semiconductor device such as a MOSFET depends on its drain-to-source current. The value can be determined using a method known as gate-current extraction.
Another way to measure the breakdown voltage is to place a small amount of material between two electrodes, and then apply an extremely high voltage. The voltage is then increased until it breaks down.
The breakdown voltage of an insulator depends on the material used, the distance between the electrodes, and the electric field strength at the contact. This is an important factor in determining the safe voltage that can be applied to an insulation.
This is the reason dielectric breakdown testing is vital, since it allows engineers to determine the maximum possible voltage for their designs. It can also be used for monitoring changes in the insulator's ability to resist voltage.
Certain conductors, like aluminum and copper, are more prone to breakdown than others. The aluminum conductor High Voltage Installation can suffer the breakdown voltage of 3 kV/mm when exposed to dry air at normal atmospheric pressure. This is why aluminum cable is rated to lower voltage than copper.
Other insulators like silicon may experience breakdown voltages as high as to 3.5kV/mm when they are exposed to air that is dry at normal pressure. This is because silicon conducts better at a lower temperatures than aluminum.
In liquids, breakdown could be caused by bubbles or small impurities. They can result in an electric field strength that is not linear between electrodes, which can increase the potential for breakdown.
For this reason, it is often a good idea to protect the conductive surfaces of a device using dielectric materials like glass or plastic. This will help protect against the possibility of breaking and the subsequent hazards associated with it.
