ELECTRICAL ENCYCLOPEDIA

What is an ACSR?   Aluminum conductor steel reinforced (or ACSR) cable is a specific type of high-capacity, high-strength stranded cable typically used in overhead power lines. The outer strands are aluminum, chosen for its excellent conductivity, low weight and low cost. The center strand is of steel for the strength required to support the weight without stretching the aluminum due to its ductility. This gives the cable an overall high tensile strength.. continue.. Construction, Application and Specification of an ACSR   Overhead transmission line conductors are usually ACSR or AAC to B.S. 215, although the aluminium alloy conduc­tors to B.S. 3242 are also being used. Aluminium wires used in the AAC and ACSR are hard drawn and of 99.5% purity aluminium with a specific resist­ance of 2.8264 microhm cm. This gives a conductivity of 61 % I.A.C.S. .. continue..

Voltage Regulator Basic Definition   A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. A voltage regulator may be a simple "feed-forward" design or may include negative feedback control loops. It may use an electro-mechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.. continue.. Voltage Regulator as an Electronic Device   voltage regulator,  any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. Such a device is widely used in motor vehicles of all types to match the output voltage of the generator to the electrical load and to the charging requirements of the battery. Voltage regulators also are used in electronic equipment in which exces...

Bundled Conductors inTheory   Extra high voltage lines corona causes a large problem if the conductor has only one conductor per phase. Corona occurs when the surface potential gradient of a conductor exceeds the dielectric strength of the surrounding air. This causes ionization of the area near the conductor. Corona produces power loss. It also causes interference with communication channels. Corona manifests itself with a hissing sound and ozone discharge. Since most long distance power lines in India are either 220 kV or 400 kV, avoidance of the occurrence of corona is desirable.. continue.. Aerial Bundled Conductors   Aerial bundled cables (also aerial bundled conductors) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. This contrasts with the traditional practice of using uninsulated conductors separated by air gaps. The main objections to the traditional design are that the multi...

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...

Ray Gun   Rayguns are a type of fictional directed-energy weapon. They have various alternate names: ray gun, death ray, beam gun, blaster, laser gun, phaser, etc. They are a well-known feature of science fiction; for such stories they typically have the general function of guns. According to the stories, when activated, a raygun emits a ray, typically visible, usually lethal if it hits a human target, often destructive if it hits mechanical objects, with properties and other effects unspecified or varying. Real-life analogues are electrolasers, electroshock weapons which send current along an electrically conductive laser-induced plasma channel.. continue.. LASER Definition   Definition: A laser is a device which is built on the principles of quantum mechanics to create a beam of light where all of the photons are in a coherent state - usually with the same frequency and phase. (Most light sources emit incoherent light, where the phase varies randomly.) Among the o...

Electric Shock Weapon   An electroshock weapon is an incapacitant weapon used for subduing a person by administering electric shock aimed at disrupting superficial muscle functions. One type is a conductive energy device (CED), an electroshock gun popularly known by the brand name "Taser", which fires projectiles that administer the shock through a thin, flexible wire. Other electroshock weapons such as stun guns, stun batons, and electroshock belts administer an electric shock by direct contact. A shockround is a piezo-electric tip for a projectile that generates and releases electric charge on impact.. continue.. How Stun Gun Works?   On th­e old "Star Trek" series, Captain Kirk and his crew never left the ship without their trusty phasers. One of the cooles­t things about these weapons was the "stun" setting. Unless things were completely out of control (as they frequently were), the Enterprise crew always stunned their adversaries, rendering them...

What is an Electric Catfish?   Electric catfish is the common name for the catfish (order Siluriformes) family Malapteruridae. This family includes two genera, Malapterurus and Paradoxoglanis with 19 species.Several species of this family have the ability to produce an electric shock of up to 350 volts using electroplaques of an electric organ. Electric catfish are found in tropical Africa and the Nile River. Electric catfish are usually nocturnal and feed primarily on other fish, incapacitating their prey with electric discharges.... continue.. Electric Catfish   A popular type of fish in modern aquariums is the electric catfish, mainly due to their dynamic natures. It is originally native to Africa with the densest populations in the Western and tropical regions, including the Nile River. It is an aggressive and carnivorous creature that will attack and consume almost any prey up to half of its own size. It lurks in rocky areas in dark freshwater, waiting for prey to h...
