| Insulation is an important part of any electrical and electronic system. More and more insulation materials are being introduced to cope with the high speed electronics and integrated circuits. Different types of insulation materials have different applications in industry. Power electronics devices have a higher trend towards integration and increase in density nowadays. Main motives towards evolution of power electronic devices are to increase the reliability, thermal and electrical performances by achieving hybrid integration. In this paper, we have reviewed different insulation materials essential for protection of electrical and electronics system, factors that result in degradation of insulation materials i.e. power electronic convertors and adjustable speed drives, designs used to improve the power quality of medium voltage grid stations and effect of transient frequency on service life of insulation materials. Moreover the degradation of insulation materials and factors affecting insulation are also been discussed. |
