During the lightning activities every air terminal has the equal chances to be hit by the lightning fashes and it produce electric feld in the surrounding. Therefore, with the passage of time when the lightning air terminals become aged due to acidic rain and chemical contamination, lightning air terminal (LAT) bypasses on side edges takes place which has not been given much attention by the researchers. A modifed lightning protection system (LPS) was proposed in this paper using experimental and electromagnetic feld approach. One of the LAT on diferent geometrical structure was selected as sacrifcial point in order to reduce the chances of LAT bypasses. The modifed protection system can be referred by diferent standard to make sure buildings protection. All the experimental work was done using high voltage impulse and ANSYS/MAXWELL was used as a simulation tool. The modifed protection technique will help diferent standards to provide comprehensive protective measures against lightning.

Pakistan is facing a drastic scarcity of electricity for the last two decades. Most of the areas in Pakistan have no access to electricity especially in Balochistan where most of the population has no electricity and water supply. Concerning the electricity issues, this research study is investigated to design a technical and economical hybrid system for the remote areas of Balochistan. For this purpose, three remote sites have been selected named Gujar village in district Awaran, Plantak in Washuk, and Shahrak village in Kech of Balochistan. Proposed sites are analyzed to fi nd the potential of renewable energy i.e. Wind and solar in the targeted sites of Balochistan. The wind and solar potential data are taken from the PMD, NREL, and NASA websites. For the selected sites, three models have been designed in Homer Pro software by using diff erent component combinations. These components include a fuel cell, generator, batteries, hydrogen tank, electrolyzer, Wind and Solar modules, and Converters. These models are connected to the grid to sell back the excess energy to the grid through net metering. After simulation and optimization, the most feasible and economic solution is decided that is based on NPC, COE, initial cost, and operating cost.
