Abstract

Within paper is presented the new installation for temperature-rise test, according to IEC 62271-202/2014 of high voltage/low voltage prefabricated substations with powers up to 1600 kVA and voltages up to 52 kV composed from a three-phase, low voltage AC supply with motor-generator group and a three-phase, high voltage AC supply realised within High Power Laboratory (HPL) of ICMET-Craiova with three single-phase groups autotransformers-transformers. The realized installation is an alternative to temperature-rise tests electrical equipment because it uses a supply different that motor-generator one. In second part there are presented experiments performed on a prefabricated substation.
