What role did each play in the development of the electrical utility industry? What were the advantages and disadvantages to the AC and DC electricity distribution systems? Why did AC win? Tesla‚ Westinghouse‚ and Edison were all key people in the history of the development of the electrical utility industry. Nikola Tesla improved

was electricity. Thomas Edison invented the first successful electric light bulb and the first electrical power distribution company. Making Electricity People make electricity at electric power stations. Machines called generator make electricity from other forms of energy such as coal‚ falling water‚ wind‚ gas‚ oil or atomic energy. Wires or conductor are the ones that carry or conduct the electrical current. Using Electricity We use the energy of electricity in our homes‚ schools‚ businesses

Total Power or Apparent power is the combination of real power and reactive power. Total power is measured in kilovolt-amperes (kVA) and is totalized by the electric billing meter in kilovolt-ampere-hours (kVAH). ELECTRICAL LOADS: In general‚ electrical systems are made up of three components: resistors‚ inductors and capacitors Capacitive Load The power factor for capacitors is leading. Therefore capacitors are installed to counteract the effect of reactive power used

there is a need to change voltage‚ current of frequency of electric power. The power range of these converters is forming some mill watts (as in mobile phone) to thousands of megawatts in an HVDC transmission system. With classical electronics‚ electrical currents‚ and voltage are used to carry information‚ where as with power electronics‚ they carry power electronics becomes the efficiency An inverter converts DC to AC‚ and also changes voltages. In other words‚ it is a power adopter. It allows

transmission line losses‚ the input impedance of the stub is purely reactive; either capacitive or inductive‚ depending on the electrical length of the stub‚ and on whether it is open or short circuit. Stubs may thus be considered to be frequency-dependent capacitors and frequency-dependent inductors. Because stubs take on reactive properties as a function of their electrical length‚ stubs are most common in UHF or microwave circuits where the line lengths are more manageable. Stubs are commonly used
