Question

What are the advantages or disadvantages of using polyphase electricity with more than three phases?

Answer 1

advantages:

1)By increaing the number of phases the power transfer can be increases

2)The rating of motors and generators can be increased

3)Bulk amount of power can be generated and transmitted

4)Due to more phase the operating voltage can be increased and the losses can be minimimised

5)efficiency will be improved

disadvantages:

1)cost of the conductor will be increases

2)Communication and radio interference problems
