Answer Posted / umesh chandra bhuyan
Answer is very simple,so don't think too much on this.we know voltage is the potential difference between two points or levels. So that it is always measured in two wires only. So that multimeter have 2 probe only.so in single phase it is potential difference between one phase (higher potential zone) and a neutral (zero potential zone).this all about phase voltage. In case of line voltage (3phase system) this is the difference between phase to phase.all 3 phases are 120' out of phase. Example-when r phase reaches its maximum y phase is just behind it but b phase is nearer to zero as it just starts.so all two phase are act as incoming and other behave as return for other two.
Hope u will satisfy........
