Current balancing procedure

  • Thick over all possible combinations of phase load changes at each 3-phase connection point for either single-phase supplies or loads.
  • When all selections have been made, consider the order in which loads are connected.
  • It is so as not to exclude the best combinations of load phase connections.
  • The best set of connections will minimize the imbalance for each 3-phase sections of feeder between supply/load connections.
  • When planning a new feeder, the supply/load phasing selection is an important factor in producing the best design.
  • When balancing an existing feeder it is the need to get the required balance with the minimum number of changes to load phasing.
  • To achieve this manually is a difficult experiment.
