3 Phase Star Connection

Voltage, Current and Power in 3 Phase Star Connection: 3 Phase Star Connection – Figure 9.21 shows a balanced three-phase, Y-connected system. The voltage induced in each winding is called the phase voltage (Vph). Likewise VRN, VYN and VBN represent the rms values of the induced voltages in each phase. The voltage available between any pair of …

Polyphase System

Polyphase System: In an ac system it is possible to connect two or more number of individual circuits to a common polyphase source. Though it is possible to have any number of sources in a polyphase system, the increase in the available power is not significant beyond the three-phase system. The power generated by the …
