Aging phenomena of paper-oil insulating system under different voltage stress

Popis výsledku v původním jazyce

Until now not much attention was paid to behavior or insulating materials unde different voltage stresses. For decades, the applied research was done generally under AC voltage. As power electronics was involved in drives and dominated instead of DC drives, new troubles with lifetime occurred. The great influence of higher harmonics does not affect operating parameters only but also it limits the lifetime of the insulation system. Steep voltage rises are generated by power electronics, significant overvoltage occur. As economic aspects play its role, often not sufficient filters are utilized to reduce switching overvoltage, which leads to additive voltage strassing. recently also DC transmission is planned or even build. Dc transmission is especially interesting at very high voltage levels, which brings the space charge phenomena together. Space charge is causing electric field distribution with unexpected stresses affecting the isnulation material. There is also the effect of voltage
