The circuit voltage will vary with vary with time since the load demand caries with time. This variation for the end of the feeder is shown in Dig. 10. This is not a huge variation since the load factor for the circuit is rather high. However this could get worse for larger peaks associated with heating and cooling seasons.
Fig. 11 shows the substation loading for all three phases. The load is unbalanced but the individual phase loads still have the same consumption pattern.
