Precautions For High Voltage Installation
High voltage electrical installation tester power lines are often located on utility poles however, they could also be buried. Regardless of where you work it is essential to be aware of the appropriate precautions for working with high voltage electricity.
A shock to the electric heating installers near me circuit is the most dangerous. This can cause serious injury or even death.
Insulation
Insulation is a crucial aspect of high-voltage installations and it needs to be maintained at the appropriate levels to protect against failure, but also avoid electric shocks. Insulation acts as an obstruction between electrodes as well as other circuit components and makes it impossible for them to get them in contact with one another. This can lead to injury or even death.
Various materials are used to create insulators. The most popular was rubber material due to its ease to manufacture and could stand up to the toughest conditions. Plastics have replaced rubber as the most preferred material in high-voltage installations.
Some plastics are more durable than others, and you must look at the properties of every insulation material when deciding on which is the most suitable for your needs. You need to be aware of how each material will resist, how tough it is and how flexible and how it fares with the effects of abrasion, moisture, and other aspects.
The properties of thermal and chemical properties are also important. These properties can assist you in selecting the ideal material for your requirements.
When working with insulators in a high-voltage environment, it is important to be sure that they are constructed of an material that is able to withstand the heat and pressure. This means you must select a material that is able to stand up to temperatures of at minimum 1000 degrees and also be resistant to humidity.
It is also important to look for insulators that can withstand fire and other dangers. This can include a product that can resist sunlight and ozone. It is also waterproof and is resistant to chemical and oil.
It is also essential to find insulation that is designed to withstand the extreme tensions associated with power transmission. These insulators can be suspended insulation, strain insulators or shackle insulation.
These insulators can be utilized to shield power lines from sharp corners or dead ends. Depending on the line's voltage, the insulators may consist of several porcelain or glass discs, which are joined to each other by metal links.
Sharp Points
Conductors with sharp edges or sharp points increase the chance of dielectric breakdown in high voltage spikes. Thankfully, most manufacturers are aware of this problem and have made a point of using heat-shrink tubing containing a suitable dielectric strength. A well designed system also takes measures to minimize the dangers of improperly trimmed insulation, a common cause of problems for the experienced high-voltage installer.
A best practice to ensure a safe, efficient installation is to employ a quality contractor. The most skilled contractors are acquainted of the dangers that come with high voltages and are able to implement a safety plan. This is the most challenging part of the procedure. It is vital that each person on the team is aware of the job they are assigned and understands the high-voltage terminology.
Dust
To ensure the safety of employees and avoid injury, it is crucial to ensure that dust does not get into a high voltage installation. This can be accomplished by using a dust-proof construction. It is also recommended that a protective cover be applied to the insulation.
Metal dust and insulating fibres are frequently mixed in high-voltage equipment. This is because they have similar characteristics of discharge and movement and a small amount dust can dramatically reduce the breakdown voltage of an air gap.
It is unclear what is electrical installation impact these impurities have on the nature of the breakdown of an air gap. A series experiments were conducted to understand the discharge and motion behavior of these materials.
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. When the voltage is less than 7 kV, particles are mostly moving to the upper electrode. They bounce violently between electrodes once it is 14 kV.
A series of tests using 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 high voltage contact sate (or distant sate), distant sate (or jump sate).
When the metal dust was present in contact sate, it moved towards the upper electrode , and its movement area created a certain columnar dust region between the electrodes. The concentration of dust in this area was low.
The insulating fibers, on the other hand they didn't move when the voltage was low, but started to rise when voltage increased. The resultant jumps between electrodes were quite fascinating.
During the test, voltage was increased from 7 kV to 16 kV. The metal dust and insulating filaments began to move rapidly. The insulating fibers began to bounce and lift up quickly between the electrodes. This caused a sudden change in their motion. At the same moment there was a significant amount of dust particles were released from the discharge area and caused an explosion.
Voltage Breakdown
In the event that an insulator experiences rapid change of its electrical properties, it is referred to as breakdown. This is caused by the local electric field strength which is greater than the dielectric force of the material. This can happen in air or any other insulator and can cause fire, burns or even explosions.
Based on the material used and the shape of the object, it is possible for breakdown to occur at different voltages. It is therefore essential to test the materials used to construct high voltage installations.
For instance, the breakdown voltage of a semiconductor device such as a MOSFET is determined by its drain-to-source current. The value can be determined by using a method known as gate-current extraction.
Another method to determine the breakdown voltage is to put a piece of material between two electrodes and then apply a high voltage. The voltage is then raised until the material has broken down.
The breakdown voltage of an insulator is based on the material used and the distance between electrodes, as well as the electric field strength at the point of contact. This is an important factor in determining the safe voltage that can be applied to an insulator.
Engineers can utilize dielectric breakdown tests to determine the maximum voltage that their designs are able to handle. It is also utilized to observe changes in the insulator's capacity to endure the voltage.
Certain conductors like aluminum and copper are more susceptible to break than other. For instance, aluminum could suffer a voltage of up to 3 kV/mm exposed to dry air at normal atmospheric pressure. This is the reason why aluminum cable is rated for 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 at lower temperatures than aluminum.
Impurities, such as bubbles, can cause liquids to degrade. This can result in the formation of a non-linear electric field between electrodes, which can increase the breakdown potential.
It is a good idea to protect the surfaces of conductive devices using dielectric materials such as glass or plastic. This can help safeguard against the possibility of breaking and the hazards that go along with it.
