HNC Electrical Engineering - Essay ExampleFortescue, who introduced the method around 1918.....(1)However, it remained difficult to understand the three-phase system on the job(p) under this concept, as any change in the electromotive force or current in any single phase could result in the like changes in other two phases as well. Therefore, only two-phase alternating current was used in the forcefulness systems and it had 90-degree difference between the phases.(2n) Hence the two-phase power-generating concept was developed. However, we flummox evidence of using two-phase generators by connecting two single-phase ones, as early as 1890s........(2)In simpler terms, three-phase power system is the one that uses three different telegraphs. One wire lowlife be a neutral cable, which facilitates the system to use higher voltages while transmitting low voltages in domestic appliances. However, those machines that use high voltage allocations, the neutral cable requirement is not t here as negligible lodges are connected between the phases.In three phase power systems the power load is well distributed, as all the three wires have same magnitude of current with balance power load. Most of the countries have their receive color-coding of the wires to distinguish the same in case of repairs. The three-phase power system is the widely used power in all industries, as it has balanced power load with uniform phase angle difference. However, the requirement of the household appliances and applications mess be met with the single or two-phase systems as well.All electric motors are the fine fount of three-phase power usage, as a three phase induction motor runs efficiently and has high starting torque with trouble-free design. The application of such motors can be found in fans, blowers, compressors etc. While these are medium and large size motors, application of very small three phase motors can be found in computer fans etc. The main advantage
