It is very important to prevent power surge powers with the equipment and hazard shock to people…
There is more to your electrical system than function and safety. For example, lighting contributes to the overall appearance and atmosphere of your home and office, and recessed lighting is popular now for its clean…
-There is some danger. Extreme caution needs to be taken when working with electricity since mistakes can potentially lead to fire or electrocution.…
These place a duty on employers to assess all foreseeable risks associated with work activities involving electricity. Employers are required to install safe systems of working, with well-maintained equipment, covering everything from power lines to kettles. All installation and repairs should be undertaken by a qualified electrician or those who have appropriate technical knowledge, though some minor repairs, inspections, fitting of plugs, etc may be undertaken by suitably trained staff.…
Wires, lights, and more wires, is the average thought of many people when the job electrician is spoken upon them. In Electricianing I will be taking on an adventure farther than lights and wires. Being an electrician, I have to face a lot of interest, journeys, and obstruction. Electricianing is not just one field base, there are multi sub-fields. Allowing me to branch out, explore and discover the field I accord to .…
The electrical equipment that is operational in the working environment also poses some threat and hazard to the people handling the equipment. There are chances of electric shock and burn injuries, electrical shorts and fire, or even electrocution. In order to prevent electrical accidents from occurring, it is essential for the equipment to be inspected on regular basis, and moreover, any equipment that is…
Human beings are well accomsisted with the electrical and the components .we may live without having food and shelter but we can’t live without electricity. We the humans are efficient in production, but are not as much efficient in transmitting .The percentage of loss of power during transmission and distribution is approximated as 26%. The main reason for power loss during transmission and distribution is the resistance of wires used for grid. The efficiency of power transmission can be improved to certain level by using high strength composite over head conductors and underground cables that use high temperature but, the transmission is still inefficient. According to the World Resource Institute (WRI), India’s electricity grid has the highest transmission and distribution losses in the world – a whopping 27%. Numbers published by various Indian government agencies put that number at 30%, and greater than 40%.…
In electricity supply systems, an earthing system or grounding system is circuitry which connects parts of the electric circuit with the ground (electricity), thus defining the electrical potential of the conductors relative to the Earth's conductive surface. The choice of earthing system can affect the safety and electromagnetic compatibility of the power supply. In particular, it affects the magnitude and distribution of short circuit currents through the system, and the effects it creates on equipment and people in the proximity of the circuit. If a fault within an electrical device connects a "hot" (unearthed) supply conductor to an exposed conductive surface, anyone touching it while electrically connected to the earth will complete a circuit back to the earthed supply conductor and receive an electric shock.…
Electricity is good servant but bad master. It can prove to be very dangerous if circuits are not properly protected. The major fault that appears in electrical network or equipment is termed as short circuit. In short circuit, the supply phase and neutral or earth is short circuited accidentally due to foreign metallic substance coming in contact with phase & neutral or earth or due to overload thereby damaging the insulation resulting in short circuit i.e. directly connected resulting in heavy current flow called "short circuit current". This high current heats up the terminations, switches, plugs & cable due to which temperature rises to such a high degree that it is sufficient to generate sparking which further leads to fire.…
I’m forwarding to you a call placed from 212-555-1234 to 718-5555678. Look for it on trunk 067.…
A day-in-the-life can consist of connecting all types of wires and circuit breakers, outlets, and a host of other components. Their use of tools include: ammeters, ohmmeters, voltmeters, oscilloscopes, and other equipment used in electrical testing. Their work includes making regular assessments of electrical equipment and electrical systems. Most of their work involves adding and replacing wires, fuses, circuit breakers, connections, and much more. And, the work is achieved under a variety of conditions. At different times on the job, electricians are required to follow safety rules and guidelines. People with a careful eye for detail, good working habits, and great work judgement might consider becoming electricians. Electricians need to know how to read blueprints, install, and connect and test electrical devices. They must also be familiar with local and federal electrical regulations and codes. A good understanding of electrical systems and strong manual labor is required to be effective on the job.…
10. Where do we connect a fuse: with live wire or with neutral wire? 11. What is the resistance of an air gap? 12. Name two safety measures commonly used in electric circuits and appliances. 13. Two metallic wires A and B are connected in parallel. Wire A has length l and radius r, wire B has a length 2l and radius 2r. Compute the ratio of the total resistance of parallel combination and the resistance of wire A. 14. What is the meaning of the term ‘frequency’ of an alternating current? What is its value in India? Why is an alternating current considered to be advantageous over direct current for long-range transmission of electric energy? 16. An electric wire is stretched to increase its length by 25%.By what % will the resistance be increased and what will be increase in its resistivity?…

Electricity is transmitted at high voltages (110 kV or above) to reduce the energy lost in long distance transmission. Power is usually transmitted through overhead power lines. Underground power transmission has a significantly higher cost and greater operational limitations but is sometimes used in urban areas or sensitive locations.…
