چکیده:

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 insulating medium and a new transformer construction solves the problems and guarantees the preventation of any ccnsequential damages. Physics, construction and function of SF 6-insulated instrument transformers are described. Results from field experiences over a a period of more than 10 years show the reliability of this new safety concept.
