High voltage.

What is high voltage.

ACSR

High Voltage is the electrical voltage between the power lines exceeding 1000 volts or more.

Why use high voltage

Power system with high voltage electricity can be sent to a distance. And the loss of electrical power system under a low voltage. The power transmission efficiency. Must be delivered with high voltage almost all

High voltage is dangerous, however.

Because high voltage is the voltage very high compared with the low voltage. With common household appliances (220 volts), high voltage is able to jump over the air. Or insulators have approached the object or creature. Without touching or touching wires. If the object is within a high voltage dangers that can jump over it. This will depend on the risk level of the voltage of the high voltage By the high-voltage electricity can jump across the stage, it is extremely remote. High voltage is dangerous genie. The statistics have been danger of high voltage in the service of the MEA. Deaths per year, nearly 100 injured and disabled people.

We do know that it is a high-voltage power lines.

Due to high voltage power lines is dangerous to jump over, so they have to hold the power cord. With an insulating material. To some extent with the high voltage. Insulators used mainly to do with ceramic floors. Hand shaped like an inverted bowl called insulators. Therefore, we can observe that the high voltage power lines. From the power line insulators with layers. The Class of insulators. To indicate the voltage level of the high voltage. Observing that the high voltage Another is. The height of the power cord. High voltage power lines. Usually elevation of 9 meters above the ground from the power lines above. Usually the voltage over the power lines below.

High voltage power lines are insulated or not.

High voltage power lines, most of the electricity used by road or field. Most are not insulated, or if there is insulated cover only some of which are considered unsafe to touch or touch. Insulation shall be secured with thick insulation. Are overlain by a thousand Shield (Shield) and a shell on top. The cable is heavy so it can not lean on the power poles are not.

Knowing the types of electrical cables

Cable-Types

To know the types of electrical cables can help you choose and use the right wire for your application at home as there’re various types and prices of wire and cable in the market. It is very important to use and keep any type of cables safely to prevent us from unpredictable danger that may happen at times.

Aluminum Wiring

It is the cheapest and most dangerous wiring that is still being used because it’s easy to bend and shape. But most people don’t know that this kind of wire has the lowest quality and can cause a fire in your home if it gets damage or becomes overheated. Aluminum wire is cheap and easy to find but is not recommended to be used if you care about danger.

Copper Wiring

When it comes to good quality electrical cables, this one is standard material that many electrical contractors choose to work with. It is a little bit expensive due to the performance of itself but it’s still a good choice for people who care about danger that may have caused by electrical cables in your house. Most of time, it’s used for underground purposes, for example, connecting of wire ways, channels, tracks and conduits to guarantee the safety of the underground. Moreover, the copper wiring can also be used for poor ventilation area.

Silver Wiring

This one has the highest quality with very expensive prices which is rarely used because it is harder to bend and shape.

However, the materials of the electrical cables are what we should pay attention about as well. Each of wiring, even though how expensive it is, cannot be 100% trusted as we all know that electricity is dangerous and can easily cause massive troubles so it’s best to ask or consult with a professional to ensure the safety and to understand all of the electrical cables more.

 

Electrical and Electronic Principles and Technology, 3rd Edition

John Bird, “Electrical and Electronic Principles and Technology, 3 Ed”

MgH | 2007 | ISBN: 0750685565 | 432 pages | PDF | 3,6 MB

In this book John Bird introduces electrical principles and technology through examples rather than theory – enabling students to develop a sound understanding of the principles needed by technicians in fields such as

electrical engineering, electronics and telecommunications. No previous background in engineering is assumed, making this an ideal text for vocational courses at Level 2 and 3, foundation degree and introductory courses for

undergraduates.

The book presents a logical topic progression rather than following the structure of a particular syllabus. However, the coverage of this new edition has been brought fully in line with the electrical and electronics units of the

2007 BTEC National specification. It is also designed to cover the requirements of the BTEC First specifications.

New material in this third edition includes brand new chapters on semiconductor diodes and transistors as well as added sections on batteries, fuel cells and alternative and renewable energies, relative and absolute voltages,

self and mutual inductance, and virtual test and measuring instruments.

Support material for tutors is available as a free download at http://textbooks.elsevier.com:

* Instructor’s manual with full solutions and suggested marking scheme for all 7 revision tests in the book

* Solutions manual with worked solutions for about 400 of the further problems in the book

* Electronic files for all illustrations in the book

* New colour layout helps navigation and highlights key learning points, formulae and exercises
* 400 worked problems and over 1,300 questions, all with answers
* Fully up to date with the 2007 BTEC National specification
* Free lecturer support material available via textbooks.elsevier.com

Learning AutoCAD Electrical 2014

In this training course for AutoCAD Electrical 2014, expert trainer Shaun Bryant guides you through the tools and techniques you can use to create your electrical CAD designs. With AutoCAD Electrical you get a huge selection of symbol libraries and features specific to electrical engineering. Shaun takes you through these features and how to use them step by step in short, easy to understand lessons.

You will begin this tutorial with a walk through the AutoCAD interface, as Shaun shows how to access the electrical design toolset. Each lesson is designed to build on the last, ensuring that you are not inundated with too much information at once, which will increases your retention of the material. Some of the topics that are covered include; workflow basics, schematic wiring, accessing and using electrical symbols, editing your schematics, creating panel layouts, using custom components, PLC Modules, and automation tools. Those features are just a small example of the over 9 hours of top quality video training you get in this professional tutorial.

Once you have completed this computer based training course for AutoCAD Electrical 2014, you will have a comprehensive understanding of the tools and techniques Autodesk has to offer in this popular software program.
