Precautions For High Voltage Installation

High voltage electrical power lines can be set up on utility poles but they are also buried. Whatever the location you work in it is essential to be aware of the correct precautions for working with high voltage electricity.

The most significant risk is an electric shock. This could cause serious injuries, or even death.

Insulation

Insulation is an essential component of high voltage installations. It must be maintained at the right levels to prevent failure and electric shocks. Insulation acts as an obstruction between electrodes as well as other circuit parts which makes it impossible to get them in contact with one another. This could cause injuries or even death.

Insulators can be made of different materials. Historically, rubber was the most popular material because it was simple to manufacture and was well-suited to the most extreme conditions. However, plastics have now replaced it as the preferred material in most high-voltage applications.

Some plastics are more resilient than others. You must carefully consider the properties of each insulation material before deciding on which is the best for your project. You need to know how each material is able to resist, how durable it is as well as how flexible it can be and how it fares with the effects of abrasion, moisture, and other elements.

The properties of thermal and chemical properties are also important. These properties will help you choose the right material for your application.

You must ensure that insulation is resistant to pressure and heat when used in high voltage settings. You should choose an item that can withstand temperatures of up to 1000 degrees as well as humidity.

Additionally in addition, 3 Phase electrical installation – http://sebongshop.dgweb.kr/bbs/board.php?bo_table=free&wr_id=364931 you should look for insulation that is resistant to fire and other hazards. This could mean materials that are waterproof and resistant to oil and chemicals or even a material capable of defending against sunlight and the ozone.

It is essential to look for insulators that can stand up to the extreme tensions that are associated with power transmission. They can be suspended insulators, strain insulators or shackle insulation.

These insulators are utilized to cover dead edges or sharp corners on power lines where a strong tension load is expected. They can be made up of ceramic or glass discs which are connected with metal links depending on the voltage.

Sharp Points

Conductors with sharp edges or points increase the risk of dielectric breakdown during high voltage spikes. Fortunately, many manufacturers are wise to this problem and have made a habit of employing heat-shrink tubing with adequate dielectric strength. A well designed system also takes measures to avoid the risks of improperly trimmed insulation which is a frequent cause of problems for the experienced high-voltage installer.

A good rule of thumb to ensure a secure, successful installation is to choose an experienced contractor. The most experienced contractors are familiar with the dangers associated with high voltages and have a well-constructed safety plan. The most challenging aspect of this process is making sure that each employee knows his or her job and is aware of high-voltage jargon.

Dust

To ensure the safety of employees and avoid injuries, it is essential to ensure that dust doesn’t enter a high voltage installation – http://mocha.paylog.kr/bbs/board.php?bo_table=free&wr_id=365719. Dust-proof structures are a good choice. It is also recommended that a protective cover be applied to the insulation.

High voltage equipment usually employs metal dust and insulation fibers. Because they have similar movement characteristics and discharge characteristics even a small amount of them can reduce the breakdown voltage in an air gap that is open.

However, the effect of these two impurities on breakdown of an air gap is still an unknown. A series of tests were conducted to better understand the discharge and motion of these materials.

Figure 10 shows that the lifting voltage for metal dust fluctuates as the particle size decreases however, the motion law is the same. When the voltage falls below 7 kV, particles are primarily moving towards the upper electrode. They bounce violently between electrodes once it reaches 14 kV.

In order to observe the discharge and movement of these two materials in detail the tests were conducted using the aid of a high-speed camera. The results show that the movement of metal dust and the fibers that insulate can be separated into three states: close contact Sate, distant sate and jump sate.
