Three phase power is a method of electric power transmission using three wires. Three phase power systems may have a neutral wire that allows the system to use a higher voltage while still allowing lower voltage single phase appliances. In high voltage distributions, it is not common to have a neutral wire, as the loads can simply be connected between phases.
the connection here meant for the connection of windings in three core or limbs of a transformer. it might be delta or star connected.
single phase, double phase & three phase
The answer depends on what is meant by "normal phase".

There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
Yes, there is a difference between single phase and three phase circuits.
Three phase is ac
You don't. A three phase motor will not start unless it is connected to a three phase supply.
Three phase or two phase? Three phase requires three large wires for the current needed
It must be a three phase supply service to run a three phase motor.
Any where that a three phase supply distribution is needed to operate three phase equipment.
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
