BASICS OF SURGE PROTECTION IN AC SYSTEM

What is the basic definition of a Surge? 
A surge is a sudden gust of something or a very sudden and dramatic increase. (noun). To surge is to quickly and suddenly move as part of a crowd, to increase rapidly and suddenly, or to cause someone to feel sudden and powerful emotions. (verb)continue..

What is a Surge Protector? 
A surge protector (or surge suppressor) is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or by shorting to ground any unwanted voltages above a safe threshold. This article primarily discusses specifications and components relevant to the type of protector that diverts (shorts) a voltage spike to ground; however, there is some coverage of other methods.continue..

When you put together a computer system, one piece of standard equipment you'll probably buy is a surge protector. Most designs serve one immediately obvious function -- they let you plug multiple components into one power outlet. With all of the different components that make up a computer system, this is definitely a useful device.continue..

The surge protector is an important, yet often overlooked part of a computer setup. It allows multiple devices to plugged in to it at one time and protects each connected device from power surges. For example, a home office may have a computer, monitor, printer, cable modem, and powered speakers all plugged into one surge protector, which is plugged into a single outlet in the wall. The surge protector allows many devices to use one outlet, while protecting each of them from electrical surges.continue..

Surge protectors are developed to protect electronic devices from the effect of power surges and spikes. These devices come in different types ranging from the most basic power strips to surge protectors for a whole house.Surge protector is an electric device that protects electric appliances from being damaged due to voltage spikes. It is capable of maintaining safe threshold of voltage running through electric devices. Most surge protectors feature multiple outlets. These are ideal for a computer setup requiring different devices like printers, scanners, routers, laptops and other gadgets which need a lot of outlet to plug them into one power source all together.continue..

Surge arrester is described by NEC as a protective device for limiting surge voltages by discharging or bypassing surge current on an electrical system to earth or ground. It also prevents continued flow of follow current while remaining capable of repeating these functions. In other words, a surge arrester’s purpose is to protect equipment or the system from damage due to transients.
In the past, they are known as lightning arresters due to the fact that they were primarily designed to protect equipment from lightning strikes. Nowadays, the term surge arrester has been more widely used since the device is actually effective against both lightning and switching transients.continue..

POWER SYSTEMS LOSS.COM: LOSSES IN ELECTRICAL SYSTEM

What is powersystemsloss all about?    System's loss reduction is now one of the most growing trends in every electric distribution utility. Primarily triggered by economics and regulation concerns, Transmission and Distribution companies now sets more focus in reducing losses and become as an efficient utility as possible in delivering power. Information found in this site will be very useful not only to electrical practitioners but it is also our goal to help students better understand the actual world. Thank you and lets all enjoy learning! continue..   Back to basic    n case you don't know, the power we get from our household electrical outlet didn't just appear in the thin air. It may appear that it is coming out from our walls but we all know that looks can be deceiving. Before reaching our respective homes, electric current passes through miles and miles of c...

FRUITS AS BATTERY AND SOURCE OF ELECTRICITY

Electric Fruits Project   The purpose of this project was to find out which fruit would generate enough electricity to light a light bulb and to discover which fruit would light the bulb the longest. To conduct my experiments I used a Multimeter, copper and zinc wires & electrodes, alligator clips with leads, various light bulbs and five types of fruits. continue.. Why Do Citrus Fruits Produce Electricity?   In order to generate electricity, there must be a power source and a complete circuit. When using a citrus fruit to create electricity, these rules still apply. In a simple experiment using a citrus fruit, the components of the circuit include: a lemon or other fruit, wire, two different metal elements and a small light bulb. The lemon in this circuit serves as the battery and power source. continue.. Fruit Power Project   Purpose To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or li...

ELECTROCUTION: ELECTRIC ACCIDENT THAT CAN BE AVOIDIED

Electrocution   Electrocution is a type of electric shock that, as determined by a stopped heart, can end life. Electrocution is frequently used to refer to any electric shock received but is technically incorrect; the choice of definition varies from dictionary to dictionary. However, in the vernacular, the term electrocution is used to mean: death, murder or a sudden accident caused by an electric shock. deliberate execution by means of an electric shock, such as an electric chair; the word "electrocution" is a portmanteau for "electrical execution".. continue.. Electric Shock   Electric Shock of a (human) body with any source of electricity that causes a sufficient current through the skin, muscles or hair. Typically, the expression is used to denote an unwanted exposure to electricity, hence the effects are considered undesirable. The minimum current a human can feel depends on the current type (AC or DC) and frequency. A person can feel at least 1 mA (rm...
