“…The proposed circuit diagram for this method is as shown in Figure 3. The main problem associated with series-connected devices is how to guarantee the voltage balance between the devices both at static and dynamic transient states and the same problem also being reported in [4][5][6][7][8][9][10]. If no action taken to overcome this problem, it will damage the device as its consequences.…”

Switching method in Polarization and Depolarization Current (PDC) measurement technique is an appealing area to look at, especially in terms of its behavior over time based monitoring. Previous researches on this technique did not deliberate the effect of switching method in its measurement analysis. Most of the researchers use a conventional HV relay that acts as a switching component. This paper studies the behavior of PDC measurement results and its relationship between the types of switching methods used. It is due to the research hypothesis where different switching method produces distinctive PDC measurement results. Determination of which optimal method that suit with this technique can be made by comparing PDC measurement results; the result which analogous to the reference is considered as the finest method. Two different switching methods were applied in this research, which are HV relays and series-connected of 600V, 30A, Insulated Gate Bipolar Transistor (IGBT).

While the use of power electronics based Smart Transformer (ST) is becoming a reality in traction applications, and it has been considered as an interesting option for interfacing different transmission systems, the possibility to use it in distribution systems is still considered futuristic. Replacing primary distribution transformers with ST can lead to more flexible handling of the distribution feeders, while replacing secondary distribution transformers can allow decoupling of distribution network. This paper reviews different power converter solutions for the ST focusing on modularity, control and communication needs, to meet high reliability requirements. Five topologies for the ST are considered and compared.
