(5) Three-phase four-wire system
In the low voltage distribution network, transmission lines generally use a
three-phase four-wire system; where there are three phase lines and one neutral
line N (if the neutral point of loop power supply side is grounded, the neutral line
is also called the zero line).
In the three-phase four-wire system, the wiring method of measuring instrument
is shown in Figure 4-9.
