  • Abstract
    High energy discharges in conventional oil paper insulated instrument transformers lead to explosions with disastrous consequences for the other substation equipment and the environment. The use of SF 6 gas as the insulating medium and a new transformer construction solves the problems and guarantees the prevention of any consequential damage. The physics, construction, and function of SF6-insulated instrument transformers are described. Results from field experiences over a period of more than 10 years show the reliability of this safety concept
