Trial and error approach which involves service interruption is usually carried out to resolve unbalance on phases in power distribution system. This approach might improve the phase voltage and current but the resultant effect (change) does not last for too long; thereby reduces the market value in terms of quality and reliability of supply. To enhance the performance of the secondary distribution system there is a need for an automating technology. The aim of this book is to introduce a method and technology developed for resolving imbalances in a secondary distribution system as a result of the uneven distribution of single phase load across a three phase power system. The technology developed is able to monitored, acquire/display collected data and perform self changing switching actions electronically. This action is in form of rearrangement or transfer of consumer loads. The proposed switching technology is based on open- transition switch that enables transfer or rearrangement of consumer loads in a three-phase system within Validation Methodologies applied includes System Simulator - Matlab (Simulink), Virtual Instrumentation-Lab VIEW and Hardware implementation.
