Poly-Phase System of Circuit | Alternating Current | Electrical Engineering
Poly-phase system costs more than single-phase system, but the former has many advantages over the latter. That is the reason for which at present over 90% of electrical energy used for commercial purposes is generated and transmitted in poly-phase. Some of the advantages of poly-phase system over single-phase working are as follows: (i) For a given size of frame, a [...]
