Electricity, Magnetism, and Waves Activity  Explain the science behind the scenario. SCENARIO #5:  In the science department, we have a set of magnets that we set up to show you ‘levitating magnets’.  This is the same process that is used (only at a much grander scale) with magnetic levitating trains.  Explain how the magnets must be oriented to get the trains to ‘float’ above the tracks.  Answer:

Distribution System

The final stage in the delivery of the electric power is the electric power distribution system. From the transmission system to the individual customers it carries electricity. The distribution system is connected with the transmission system and is used to lower the voltage of the transmission to medium voltage in the range of 2 kV to 35 kV with the help of transformers. This medium voltage to the distribution transformers located near the customer's premises is carried by the primary distribution system lines. These distribution transformers in turn lower the voltage to utilization voltage used in lightings, household appliances, industrial equipments etc. Through secondary distribution lines often several customers are supplied from one transformer. It is through service drops, the commercial and residential customers are connected to the secondary distribution system lines. Customers who demand a larger amount of power can be connected directly to the primary distribution system level or the sub-transmission level.
