Precautions For High Voltage Installation High voltage electrical power lines can be erected on utility poles, but they are also buried. Whatever the location you work in it is crucial to know the proper precautions for working with high voltage electricity. The biggest risk is an who installs electric meters shock. This can cause serious injuries or even death. Insulation Insulation is a crucial aspect of high voltage installations and must be maintained at appropriate levels to not only safeguard against failure but also to avoid electric shocks. It acts as a barrier between the electrodes of the device and the rest of the circuit, making it difficult for anyone to get them directly, which could cause injury or even death. Insulators can be made of different materials. Rubber was the most sought-after material because it was easy to make and could stand up to the harshest conditions. Plastics have replaced rubber as the preferred material in high-voltage applications. Some plastics are more resilient than others. It is important to consider the properties of each insulation material before deciding which one is best suited to your project. Particularly, you should be aware of the strength of each, how durable it is, its flexibility and how it handles moisture and abrasion. These properties include chemical and thermal. Knowing the resistance to acids and alkalis 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 particular needs. When working with insulators in a high voltage setting, you should ensure that they are made from an material that is able to withstand the heat and pressure. Choose one that is able to stand up to temperatures of up to 1000 degrees and humidity up to. Additionally, you should always look for insulators that are resistant to fire and other dangers. This could mean a material that is water-proof as well as resistant to oil and chemicals or even a material that is able to resist sunlight and ozone. It is also crucial to choose insulation that is designed to withstand the extreme pressures that are involved in power transmission. These could be suspension insulation, shackle insulators or strain insulators. These insulators are utilized to cover dead edges or sharp corners on power lines in which a heavy Tensile load is expected. Depending on the line's voltage these insulators could be made up of several porcelain or glass discs that are connected to each other by metal links. Sharp Points Conductors with sharp edges and points increases the chance of dielectric breakage in the event high voltage spike. Many manufacturers have realized this and have made it a point to utilize heat-shrink tubing with an appropriate dielectric strength. A well-designed system will be able to mitigate the risks of a poorly cut insulation, which is a frequent issue for high-voltage installers. It is a good idea to work with a professional contractor to make sure that you have a safe and secure installation. The most reliable contractors have a well-constructed safety program in place and are versed in avoiding the hazards associated with high voltages. The most challenging aspect of this procedure is ensuring that each employee knows the job they are assigned and is knowledgeable of the terminology used by high voltage companies. Dust In order to ensure the safety of employees and avoid injury, it is crucial to ensure that dust doesn't infiltrate a high voltage system. This can be accomplished by using a dust tight construction. It is also recommended that a protective cover be applied to the insulation. High voltage equipment usually utilizes metal dust and insulating fibers. This is due to their similar characteristics of discharge and movement and a small amount dust can greatly reduce the breakdown voltage of an air gap. However, the effect of these two impurities on the breakdown behavior of an air gap remains unknown. To better understand the discharge phenomena of these materials, a series of experiments were conducted to examine their discharge behavior and motion individually and together. Figure 10 shows that the voltage used to lift for metal dust changes slightly with decreasing particle sizes but the motion law remains the same. The particles are moved mainly towards the upper electrode when the voltage is lower than -7 kV, and they bounce violently between electrodes when it reaches the voltage of -14 kV. In order to observe the movement and discharge of these two materials in depth A series of tests were carried out using the aid of a high-speed camera. The results showed that metal dust and insulating fibres could be divided 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 movement area formed an area of dust columnar between them. The concentration of dust in this area was low. The insulating fibres on the other hand were not moving when the voltage was low but they began to rise as the voltage increased. The resulting jumps between the electrodes were quite fascinating. During the test, the voltage increased from -7 kV up to -16 in kV. Then the metal dust and Fuse Box Installation insulating fibres started to move with a ferocious speed. As the insulating fibres lifted and bounced, they shook violently between the electrodes and caused an abrupt change in motion. A large number of dust particles were expelled from this area, which caused an explosion. Voltage Breakdown Breakdown occurs when an insulator undergoes an immediate change in its electrical properties. This is due to an electric field strength locally that is higher than the dielectric strength of the material. This can happen in air or any other insulator . It could result in burns, shock or even fire. Based on the material and shape of the object, different voltages can cause breakdown. This is why testing of the materials used in high voltage Fuse Box Installation (Http://Cse.Google.Td/Url?Sa=I&Url=Http%3A%2F%2Fwebits.Samplekorea.Com%2Fbbs%2Fboard.Php%3Fbo_Table%3D01Clean4%26Wr_Id%3D59367) is vital. 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 by using a technique known as gate-current extraction. Another method of measuring the breakdown voltage is by putting the sample of material between two electrodes and applying the material to a high voltage. The voltage is then increased until it is broken. The material of an insulator, the distance between electrodes and the power of the electric field that is present at the contact determine the voltage at which it breaks. This is a crucial aspect in determining the amount of voltage is safe to apply to an insulation. This is the reason dielectric breakdown testing is so vital, since it allows engineers to determine what is the highest possible voltage for their designs. It is also used to track changes in the insulator's ability to resist the voltage. Certain conductors like aluminum and copper are more susceptible to breakdown than others. For instance, aluminum could have a breakdown voltage of up to 3 kV/mm exposed to dry air at standard atmospheric pressure. This is why aluminum cable is rated at lower voltage than copper. Other insulators like silicon can be subject to breakdown voltages of up to 3.5kV/mm when they are exposed to dry atmospheric air at normal pressure. This is because silicon conducts better at a lower temperature than aluminum does. In liquids, the breakdown of the substance can result from bubbles or small impurities. They can create an electrical field that is non-linear in the space between electrodes, which could increase the potential for breakdown. It is usually beneficial to shield the conductive surfaces of a device with dielectric materials such as glass or plastic. This will help protect against the possibility of it breaking down and the dangers that can result from it. |
