Analysis and Comparative Study of Theoretical and Practical Air Breakdown Voltages between Spherical Electrodes
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
Growth in power sector of nation is a challenge for power engineers for the protection of sensitive power equipments and their reliable operation. The major challenges in high voltage (HV) power equipments include the quality and reliability of insulators used in power equipments. The HV power equipments are generally subjected to over voltage which may be caused due to thunder bolts or switching actions. These internal and external causes of over voltages determine the safe clearance requirements of proper insulation level. Normally air is the widely used medium as an insulator in different electrical power equipments as its breakdown strength is 30kV/cm. Therefore electrical breakdown characteristic of small air gap under the different applied voltages has its great significance for the design consideration of various air insulated HV equipment. In this paper, theoretical Breakdown Voltages (BDV) of different air gaps between spherical electrodes is compared to the practical values at normal temperature and pressure.
