JUST FOR KNOWLEDGE...

1.WHAT IS SUBSTATION???
European sockets provide electric current at 230 Volts.Since, this voltage do not suffice to cover the large distance from power plant to our homes, it is raised in the power plants with the help of transformers up to 380,000 Volts.Locally, large substations or 'small transformer houses' transform to 230 Volts.A transformer is like the electromagnet.The incoming high voltage electric current generates a magnetic effect in the coil.This permeates the neighboring coil in the second electric current and generate a lower voltage: 230 Volts...

2.DO YOU KNOW???

  • The Electric eel generates up to 600 Volts of Electricity in special muscles.In this way it can defend its enemies.
  • Voltages starting from 48 Volts are considered fatal.Hence, Electric toys should have a maximum voltage of 24 Volts.
  • Power saving lamps can last 8 times longer than normal bulbs and consume only about one-fourth of the electricity.
