Three Phase Connecctions
Line Voltage and Line Current
In single phase system two wires are sufficient for transmitting voltage to the load. i.e., phase and neutral. But in three phase system, two ends of each phase are available to supply voltage to the load.
THREE
PHASE CONNECTIONS
In
single phase system two wires are sufficient for transmitting voltage to the
load. i.e., phase and neutral. But in three phase system, two ends of each
phase are available to supply voltage to the load. If all six terminals are
used independently to supply voltage to load then total six wires will be
required and it is very much costly.
To
reduce the cost by reducing the number of windings, the three windings are
interconnected in particular fashion which gives different three phase
connections.
Star-Connection:
The
Star Connection is formed by connecting starting or terminating ends of all the
three windings together. The common point is called Neutral point. The
remaining ends are left free for connecting purpose. The star connection is
shown in Figure 1.53.
Delta Connection:
The
delta is formed by connecting one end of winding to starting end of other and
connections are continued to form a closed loop. The supply terminals are taken
out from the three Junction points. The delta connections is shown in Figure
1.54.
Line Voltage and Line Current
potential
difference between any two wires of supply is called line voltage.
The
current passing through any line is called line current.loinsq ni b
