Correct Answer - Option 3 : Underground

Metadyne:

  • It is related to a third brush dynamo although includes extra windings of varistor otherwise regulator.
  • Its characteristics are equal to an amplidyne except a compensate winding in the latter which completely offsets the result of the generated flux through the load current.
  • The main function of a metadyne is to change the input of stable voltage into a stable current and uneven voltage output.
  • They are used to control large guns and controlling the speed of electric trains (underground). It can be also used as a rotary transformer/an amplifier.
