PHASE-N (phase-to-neutra voltage)
LINE-LINE (line-to-line voltage)
It is possible to switch to phase-to-neutral voltage or line-to-
line voltage only when the connection method is 3P3W3M
(three-phase three-wire three power meter method) or 3P4W
(three-phase four-wire).
• With 3P3W3M:
Normally, line-to-line voltage (LINE-LINE) is measured, but this
can be converted to phase-to-neutral voltage (PHASE-N) with
internal processing on the 3196. The line-to-line voltage is pro-
cessed so that the center of the triangle that created the three-
phase line-to-line voltage becomes the neutral point.
• With 3P4W:
Normally, phase-to-neutral voltage (PHASE-N) is measured, but
this can be converted to line-to-line voltage (LINE-LINE) with inter-
nal processing on the 3196.
