Medium voltage direct current (MVDC) transmission system are growing due to their assistive quality in conventional grid and compatibility with renewable power network. MVDC distribution links with “Mixed” overhead (OH) & underground (UG) sections could be devised based on urban planning. UG Cables or substations are indirectly exposed to lightning...

The black-box arc model is a tool that facilitates efficient research based on empirical studies in breaker design and analysis. However, its application has primarily focused on the design of ACCBs, with only a few instances of its implementation in the design of low-voltage (LV) DC circuit breakers (DCCBs) using mechanical methods. In DCCBs with...

Abstract— Pakistan is geographically suitable for the installation of Photovoltaic (PV) cells to produce electricity. Pakistan covers the maximum of its land where sunny days prevail throughout the year. The energy produced from these panels can be affectively distributed throughout and excess of it can be provided to the nearby grid. The populatio...
