Also, if you want to know how they are defined.<br> * If you want to do the necessary calculations to size the load breaking/interrupting/disconnecting devices for normal and fault conditions.<br> * If you want to know the types and sources of power line disturbances. Also, if you want to know the effects of such disturbances on the major components of the power systems and the methods of reducing these damaging effects.<br> * If you want to know the effects of using local capacitors in increasing the circuit capacity and how to size capacitors to improve the p.f. in motor circuits.<br> * If you want to quantify the effect of direct and indirect lightning strokes on overhead distribution systems. <br> * If you want to know what are the data that have to be available in order to perform any of the following studies: TRV, stability, load flow, fault/co-ordination, motor starting, reliability and switching transients.<br> * If you to know the procedure to calculate the following: basic values including base and p.u. values, load flow, fault current/voltage sensitivity, motor starting, reliability studies for simple radial systems.<br> * If you want to know how steel properties, switchboard instruments, meters, relays are defined and what are the major modules of PLC plus the building blocks of an office automation system.<br> * If you want to know the calculations to be performed if a major power transformer is to be protected against short circuits or overloads.<br> * If you want to know what are the essential programs and data for the power systems analyst (or any other individual involved in electric power distribution and studies - for that matter). . http://vepi.eu5.org/introd1.html Fri, 30 Dec 2011 10:12:10 -0800 http://vepi.eu5.org/introd1.html Overhead and underground distribution systems components, switchgear, circuit breakers, MCCs and contactors, power line disturbances, maintenance, personnel vs. equipment safety. http://vepi.eu5.org/linux.html Thu, 29 Dec 2011 10:12:10 -0800 http://vepi.eu5.org/linux.html If you are new to Linux operating system, like me, then this page is for you. I had a personal computer (desktop) with Windows 98 and Windows XP intalled on it (dual booting). I was able to convert it into a multiple boot machine i.e. Windows98, WindowsXP, Ubuntu (a distribution of Linux operating system) and simplyMEPIS (another flavour or distribution of Linux). http://vepi.eu5.org/Webspani.htm Thu, 29 Dec 2011 10:12:10 -0800 http://vepi.eu5.org/Webspani.htm PRONUNCIATION SECTION, VOCABULARY SECTION, QUESTIONS AND ANSWERS SECTION and GRAMMAR SECTION http://vepi.eu5.org/Psat0000.HTM Thu, 29 Dec 2011 10:12:10 -0800 http://vepi.eu5.org/Psat0000.HTM For simple calculations: fundamrntal, short circuit, load flow, reliability and transients. http://vepi.eu5.org/Epdmis00.HTM Thu, 29 Dec 2011 10:12:10 -0800 http://vepi.eu5.org/Epdmis00.HTM Partial: constants of electrical power systems, circuit breakers and switchgear, cables data up to 46 KV, overhead and underground distribution equipment, conductors, steel and bus works data, instruments, meters and relays as well as motors and contactors. http://vepi.eu5.org/renen2.html Thu, 29 Dec 2011 10:12:10 -0800 http://vepi.eu5.org/renen2.html Introduction: The renewable energy resources can be classified into solar energy, wind energy, energy from biomass and landfill gas, geothermal energy, wave and tidal energies. Solar energy (i.e. its effect) may be used in one of the following ways to generate electricity heating (thermal), light photons (photovoltaic), temperature gradient (in oceans and solar ponds). The wind energy is used either with horizontal-axis or vertical-axis wind turbines to convert the kinetic energy in the wind into mechanical energy (in the blades of the turbine). With biomass, any one of the following methods may be used to generate electricity: direct combustion or gasification / pyrolysis.Mthane collected from landfills or anaerobic digestion process may be used in generating electricity. Any of the available forms of the available geothermal energy (low, moderate or high temperature) can be used to generate electricity. Wave energy may be utilized to generate electricity through the use of the oscillating water column (OWC) turbine to generate electricity. From tidal energy, electricity can be generated using the bulb, rim or tubular turbines.
