This paper investigates the punch-through phenomenon in SiC Schottky Barrier Diodes (SBD) from capacitance–voltage (C–V) characteristics at high reverse bias voltage. High voltage bias application has not been possible by conventional measurement instrumentation. The authors, therefore, develop C–V characteristics measurement instrumentation which enables the application of high dc bias voltage...

Islanding detection needs are becoming a pivotal constituent of the power system, since penetration distributed generators in utility system is continually increasing. Accurate threshold setting an integral part island scheme inappropriate might cause hazardous situation. This study looked at islanding conditions as well two transient faults, such single line to ground fault and three-phase bal...

There are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. Although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

The progression towards smart grids, integrating renewable energy resources, has increased the integration of distributed generators (DGs) into power distribution networks. However, several economic and technical challenges can result from the unsuitable incorporation of DGs in existing distribution networks. Therefore, optimal placement and sizing of DGs are of paramount importance to improve ...

Today, with attention to increase in sensitive electrical equipments application in distribution networks and their susceptibility to the power quality deficiencies, the protection necessity of sensitive loads against undesirable effects of these disturbances are in focus. So, in this paper voltage sag deficiency and Dynamic Voltage Restorer (DVR) would be introduced as the most prevalent power...
