This paper presents a proposal for a LEMP simulator circuit for testing an RF-Based Lightning Detector integrated into a PQ Monitoring System to which was added the feature of Auto Correlation of power disturbances with the LEMP spectral components.
This paper calculates the lightning flashover rates of 22 kV overhead distribution line. In order to calculate the backflashover rate (BFOR), the performance of line which related to the insulator backflashover has been modeled and analyzed using Electromagnetic Transient Program (EMTP). The shielding failure flashover rate (SFFOR) and induced voltage flashover rate (IVFOR) have been calculated follow...
This paper describes about the method for harvesting the new source of renewable energy from lightning stroke in a small-scale system. It is known that lightning can produce huge scale of electricity. The restriction in harvesting the gratis lightning energy is regarding the process to detain and store the energy within a microsecond according to the typical lightning wave shape. Due to that, a small-scale...
This paper describes the design and development of a small scale system for harvesting the lightning stroke using the single impulse voltage generator. The testing conducted at high voltage lab at Universiti Teknikal Malaysia Melaka (UTeM). A new source of renewable energy from lightning return stroke is a possible contributor to solve the energy crisis. The main problem in harvesting the lightning...
The problem of providing protection for rotating a-c machines against lightning overvoltages has two parts: 1. The protection of insulation to ground, which is mainly a question of the magnitude of the overvoltage, and 2. The protection of turn insulation, which is primarily a matter of wave front. To meet the first requirement, the overvoltage to ground must be limited to a safe value. This is assumed...
