L&T SWITCHGEAR SAFE & SURE ELECTRICAL SAFETY E S P SERVICE MANUAL GENERAL 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

ENGR. JAY S. VILLAN‚ MEP-EE Introduction A multitester or multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance‚ voltage‚ and continuity; while more advanced versions may be able to provide additional data. This tool can be very useful to have around the house‚ and anyone who plans on doing electrical repairs should most definitely use a multitester for safety reasons. Multitesters can be used with the current off or on in

Electrical Conductance and Insulation OVERVIEW: Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air‚wood and plastic. Then there are things that conduct electricity and current flows through them‚ they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are

A Career in Electrical Engineering A career in electrical engineering means solving problems associated with large-scale electrical systems. Sometimes the term is used to include electronic engineering but jobs in this field involve small scale systems such as computers and integrated circuits.it might be said that a job in electronic engineering involves transmitting information and a job in electrical engineering involves transmitting energy. Alternatively electronics power transmission control

Electronics since my childhood‚ I always dreamt of developing a master hand at electrical engineering. That was my early day fascination. With more outlook and worldly knowledge I gained with the passage of time in my life‚ I understood that Electrical engineering is a vast area of study and application and it requires a lot to master it. From there on‚ I took every careful and contemplated measure to ultimately make electrical engineering as my purpose of life. I chose Electronic & Communication

Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can
