ENERGIX-Stort program energi

Insulation stressed with fast rise time repetitive voltages from high voltage power electronics

Det elektriske energisystemet står overfor store endringer i fremtiden som følge av nye forbruksmønstre og en storskala innføring av fornybare energikilder. Dette fører til at kraftsystemet må tåle nye driftsmønstre med hyppigere oppstarter, utfall og vekslinger. Høyspennings kraftelektronikk-omf...

ENERGIX-Stort program energi

Performance of dielectric liquids for land based and subsea environmental friendly transformers.

I store krafttransformatorer er det hovedsakelig dielektriske væsker som brukes for å isolere mot de høye spenningene. Ved feil brer det seg "lyn"-overslag fra spenning til jord, som ødelegger apparatet. "Lynene" kalles for streamere. Tradisjonelt har en i transformatorer brukt mineraloljer, men ...

ENERGIX-Stort program energi

Modelling of electrical prebreakdown and breakdown phenomena in insulating liquids

Det finnes ingen samlet teori for overslag i elektriske isolervæsker. Dimensjonering av store apparater som transformatorer er basert på testing og erfaring. Når nye væsker utviklet av vegetabilske væsker introduseres i gamle apparater gir dette en risko fordi erfaringer kan ikke overføres direk...

PETROMAKS-Maksimal utnyttelse av petroleumsreserver

Electrocoalescence - Criteria for an efficient process in real crude oil systems

The fundamental mechanism active in the electrocoalescence process has been identified as a formation of an electrohydrodynamical surface instability. Hydrodynamic models for drop movement has been established and verified experimentally in model systems. This far, coalescence has been studied u...

RENERGI-Fremtidens rene energisystemer

Thermal and electromagnetic performance of transformers

The transformers represent a large present value and are of great strategic importance in power systems. While the system ages there is a wish to increase loading. The transformers are threatened by reduced mechanical strength and withstand voltage from a ged materials. Increasingly complex and u...

INTSAMGEN-Internasjonalt samarbeid generelt

Project initiation on Tranformer Management btween SINTEF and Hydro Quebec

SINTEF Energy Research has allready an echange of results with IREQ. Plans were laid to strengthen this collaboration in a KMB-project that was planned started in 2005. As this application was turned down the collaboration has cooled down. SINTEF Energy Resaerch and NTNU are internationally lead...
