1. New hardware solutions in the LV network development methodology
Voltage adapter slipper (VAS) : to maintain the output voltage in the authorized range, using an electronically controlled switched transformer
Tri mono converter (TMC): to reduce the imbalance due to a single phase subscriber, using 2 transformers
In each case, to avoid a reinforcement

2. New hardware solutions in the LV network development methodology
Modelling in the present development tools : simplified by a perfect behaviour of the new equipments
Modelling in the future development tools (2006): detailed modelling of the switched transformer (VAS), refined and phase by phase calculation (TMC)
