Ampere(s), the unit of electrical current. Current is defined as the amount of charge that flows past a given point, per unit of time. The symbol I is used for current in equations and A is the abbreviation for ampere. Ampere-hour. A measure of charge (or current flow over time).

Alternating currents — The term alternating current refers to a current that reverses at regular recurring intervals of time and that has alternately positive and negative values.

Alternating current (advantages) — As compared with DC, the advantage of AC is the reduced cost of transmission by use of high voltage transformers.

Alternating currents (disadvantages) — As compared with DC, the disadvantages of AC are: The high voltage which renders it dangerous and requires more efficient insulation; alternating current cannot be used for such purposes as electroplating, charging storage batteries, etc.

Alternating current (effects) — There are several effects of the AC to consider in determining the size of wires. Accordingly, allowance must be made for: Self induction, mutual induction, power factor, skin effect, eddy currents, frequency, resistance, electric hysteresis, etc..

Ammeter — Measures the current flow in amperes in a circuit. An ammeter is
connected in series in the circuit.

Ampere — The practical unit of electric current flow. If a one ohm resistance is
connected to a one volt source, one ampere will flow.

Anode — The positive pole of a battery, or preferably the path by which the current passes out and enters the electrolyte on its way to the other pole;
opposed to the cathode.

Branch Circuit — The circuit conductors between the final over current device
protecting the circuit and the outlet(s).

A multimeter or a multitester, also known as a VOM (volt-ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter can measure voltage, current, and resistance. Analogmultimeters use a microammeter with a moving pointer to display readings. The key process that occurs within a digital multimeter for any measurement that takes place is that of voltage measurement. All other measurements are derived from this basic measurement. Accordingly the key to understanding how a digital multimeter works is in understanding this process. There are many forms of analogue to digital converter, ADC. However the one that is most widely used in digital multimeters, DMMs is known as the successive approximation register or SAR. Some SAR ADCs may only have resolution levels of 12 bits, but those used in test equipment including DMMs generally have 16 bits or possibly more dependent upon the application. Typically for DMMs resolution levels of 16 bits are generally used, with speeds of 100k samples per second. These levels of speed are more than adequate for most DMM applications, where high levels of speed are not normally required.

    Fuse low voltage fuses,medium voltage fuses,high voltage fuses,transformer fuses,surface mount fuses,PC borad fuses,Hazardous Area Type Fuses The function of a fuse is usually to prevent fire - that's the basic protection a fuse offers - between power supply and appliance there may be a few feet or metres of cable - if a short circuit occurs in the appliance, the cable could easily become overheated (due to excess current) and burn or rupture its insulation.

    Fuse is a piece of wire of a material with a very low melting point. When a high current flows through the circuit due to Overloading or a short circuit,  the wires gets heated and melts. As a result, the circuit is broken and current stops flowing.

    Isolator

    Isolator is a manually operated mechanical switch which separates a part of the electrical power system normally at off load condition.

    Isolator is device which always operate under no load condition . This is because it has no provision for arc quenching.

    It's function is to isolate the circuit after operation of circuit breaker and discharge the grapes charges to earth through earth switch.

    Also it is very useful in maintenance period.

    Generators Emd Generator,Diesel Generator,Portable Generator,Natural Gas Generator,Two Bearing Generator,Mobile Towable Generator In electricity generation, a generator is a device that converts motive power into electrical power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines and even hand cranks. Portable generators provide electricity by running a gas-powered engine. That turns an on-board alternator to generate electrical power. Power outlets on the unit allow you to plug extension cords, electric-powered tools and appliances into it. An automatic standby generator is a back-up electrical system that operates whether you are home or away. Within seconds of an outage, it automatically supplies power directly to your home’s electrical circuit breaker box. After utility power returns, the generator shuts itself off and waits for the next outage. It operates on natural gas or liquid propane gas and sits outside just like a central air conditioning unit.

    Hand Tool In order to be satisfied with the results of your work with the hand tools, you need to know their construction, how to properly sharp hand tools and also how to use the hand tools properly. Negligence or lack of knowledge will likely lead to mistakes and there is a high risk of the injury. When using the hand tools, precision and proper hand tool use are far more important than the speed of working process. Depending on the type of work that has to be done, a craftsman must own a proper hand tools; he must be able to choose the right hand tool for the work and he has to know how to use that hand tool to do a good job. Without the proper  tools and knowledge about using it, the craftsman will lose its efficiency  and quality. Tools can be divided into several groups: -    Laying out tools – Measuring and marking tools -    Impact or striking tools (hammers, mallets and sledges) -    Twisting tools or fastening tools (wrenches and screwdrivers) -    Woodcutting tools (wood saws, planes, wood chisels) -    Metal cutting tools (dies, drills, files, punches, reamers, taps) -    Holding tools (clamps, pliers, vises) -    Safety equipment (goggles, gloves) -    Grinding and sharpening tools -    Finishing tools and abrasives -    Tool storage & accessory containers

These leads connect to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). We depend on electricity constantly, and when the power goes out in a storm or there's a tripped breaker or another problem in an electrical circuit, understanding the basic components of an electrical system can help you get things running again. It's also important to know who is responsible for what portion of your electrical service. The utility company handles the line portion of your service, which includes everything up to the attachment point on your house. From there, it's called the load side, and everything on the load side is your responsibility.  An integrated circuit is a special component that contains an entire electroniccircuit, complete with transistors, diodes, and other elements, all photographically etched onto a tiny piece of silicon. Integrated circuits are the building blocks of modern electronic devices such as computers and cellphones.

    Lightening-Surge Arrestor

    Lightening-Surge Arrestor A surge arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events. Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS), this class of device is used to protect equipment in power transmission and distribution systems. (For consumer equipment protection, different products called surge protectorsare used.) The energy criterion for various insulation material can be compared by impulse ratio, the surge arrester should have a low impulse ratio, so that a surge incident on the surge arrester may be bypassed to the ground instead of passing through the apparatus. To protect a unit of equipment from transients occurring on an attached conductor, a surge arrester is connected to the conductor just before it enters the equipment. The surge arrester is also connected to ground and functions by routing energy from an over-voltage transient to ground if one occurs, while isolating the conductor from ground at normal operating voltages. This is usually achieved through use of a varistor, which has substantially different resistances at different voltages.

A kilowatt-hour meter is the meter that the municipality installs at a premises to measure the ammount of electricity (or units) used on a premises over the period of time. The municiple meter readers are normally sent out once a month to read these meters and calculate the KWh (units) used over that period.The units or KWh's measured are then multiplied by the electricity tarriff charged by the respective municipality. A prepaid electricity meter is a KWH (Kilowatt Hour) meter, measuring electrical consumption. The main difference is that this KWh meter counts backwards as the electricity is consumed and has a  a relay (an automatic switch) which disconnects the power when the KWh reading on the meter reaches zero. It further incorporates hardware which has the ability to decipher the pin number entered and convert it to KWh.

    Welding Shielded Metal Arc  ,Gas Metal Arc ,Flux Cored Arc ,Gas Tungsten Arc Gas ,Welders Protective Gear Boiler making is the joining of metals. What boiler making does is join metals or other materials at their molecular level with the technology we have at the moment. I say “at the moment” because welding technology is always changing, and with so many military forces relying on it to make their defense products, there are welding processes we are yet to hear about. What we know about modern boiler making is that there are four components to a weld. The four components are the metals themselves, a heat source, filler material, and some kind of shield from the air. The welding process works like this. The metal gets heated to its melting point, at the same time there is some sort of shielding from the air to protecting it, and then a filler metal is added to the area that needs to be joined ultimately producing a single piece of metal.
