3.7 Phase Diagram
Phase diagram graphically represent fundamental voltages, currents and phase angles
of the network. This view is strongly recommended for checking instrument connection
before measurement. Note that most measurement issues arise from wrongly
connected instrument (see 4.1 for recommended measuring practice). On phase
diagram instrument shows:
