the form factor of sinusoidal ac supply is 1.1,now the
voltage is given based on rms value,avg value gives rounded
valus...i dont get it from any book its my concept so is it
right?please yes or no give comment

Answer / sahil

this we do from the protection pt of view.
the insulators on the towers(ceramic disc type), their single unit is designed to protect from 11kv. this voltage is suitable according the mechanical and electrical constraints.
that's why on a 33kv tower you might see 3-5 discs of the insulator(discs never less than v to be protected from).

Answer / eeecruxkarthik@gmail.com

incoming supply is 11kv but outgoing is 433v only
transformer tapping is constant 3rd mode this is for
electricity stsndards

Answer / rishabh

because power factor of ac is 1.1.
