Lightning impulse tests on air-breakdown level in point-plane electrode configuration

In the past several decades, extensive amount of research work has been done to understand the fundamental characteristics of the electrical breakdown. Breakdown voltage is a phenomenon where the quantity of an electrical force is required to transform the electrical properties of an object. Many...

Higher gap distance between the electrodes will result higher breakdown-impulse voltage while higher breakdown-impulse voltage will produce higher field intensity. 2014-07 Thesis http://eprints.uthm.edu.my/1539/ http://eprints.uthm.edu.my/1539/1/24p%20MOHD%20DASRI%20CHE%20MOK%20%40%20ADNAN.pdf text en public http://eprints.uthm.edu.my/1539/2/MOHD%20DASRI%20CHE%20MOK%20%40%20ADNAN%20WATERMARK.pdf text en validuser mphil masters Universiti Tun Hussein Malaysia Fakulti Kejuruteraan Elektrik dan Elektronik
