Hi, To carry the Power in form of Voltage and Current up to the load center, poles or vertical insulated supports are provided at pre-determined points. For Transmission, Long poles are used while for distribution, relatively small poles in height are used. (Why) ?
Because while transmitting of power, the voltage is increased by decreasing the current through Step up transformers. If small poles are used for this high level of voltage, it may be dangerous for human beings so for safety purposes, tall poles are used to transmit power from its source to load centers. At load centers, this voltage is decreased with the help of step down transformers up to 11000/230 volts (Neutral to phase) or 11000/415 in case of phase to phase.
Since in our country, all electrical appliances are designed at 230 Volts so after lower the voltage level from 11000/230, then this electricity is supplied to the end users. It is known, and the people visited foreign countries may will have noticed that in those countries all electrical appliances are rated at 110 Volts. Most of our valued visitors may know, why all electrical appliances in foreign countries are designed at rated Voltage of 110 Volts while in our country, these appliances are rated at 220 Volts or 230 Volts?
If you don't know then you should ask from any technical expert. For the time being I tell you. It is just for human safety. There are more chances of electrical shocks in using 220 or 230 Volts in copare to 110 Volts.. 220 Volt is double to 110 Volt so it is more dangerous than 110 Volts having high pressure. God Forbids, if a person is electrocuted with 110 Volts, he or she may alive and there are rare chance for him or her to a vital accident in comparison to that individual that electrocuted with 220 Volts.
In remote MHPs, wooden poles are normally used and recommended because these plants are being constructed in far flung areas where the end users are illiterate and specially the children don't know the electricity. Since, wood is purely insulator material and doesn't pas electricity through its body and these wooden poles don't attract any body touch the pole due to electrical charges which may associate with iron poles.
In this chapter you will read the installation of Poles in detail. I hope you will get enough knowledge about installation of poles. Main task for you to do is just go to the link shared below and tap the link so that you could get accessibility to the chapter.
