Three-Phase Electric Power Explained > ENGINEERING

Three-Phase Electric Power Explained > ENGINEERING

An electrical system is comprised of three main parts: energy generation, energy transmission and energy consumers. The consumers are the loads connected to the electrical system. One of the advantages of a three-phase system is that it can supply both single-phase and three-phase loads. The latter can be connected in a star (YN) or delta (D .

3.5-Core Cables. A 3-phase system may have a neutral wire. This wire allows the 3-phase system to be used at higher voltages while it will still support lower voltage single phase loads.. It is not likely in such cases that the loads will be identical, so the neutral will carry the out-of-balance current of the system.The greater the degree of imbalance, the larger the neutral current.
