Connecting Diagrams
Y or Star connection
Connecting together the W2, U2, V2 terminals (star point) and connecting to the mains the U1, V1, W1 terminals a star connection is obtained.
The phase current Iph and the phase voltage Vph are as following:
Iph = In
Vph = Vn/3
Where:
| In: | the line current | |
| Vn: | the line voltage |
Δ or Delta connection
Connecting the end of each winding to the beginning of the next winding a delta connection is obtained.
The phase current Iph and the phase voltage Vph are as following:
Iph=In/3
Vph= Vn
Star-Delta starting
