SINTEF Energy Research is engaged in research, development work, routine-, type- and field tests for manufacturers, suppliers and users of electrical equipment.

Tests with voltages up to 800 kV AC, 800 kV DC and 2000 kV lightning impulse can be run in our high voltage laboratories. These laboratories are also equipped for making rain, snow, ice, pollution, condensation, salt fog and measuring leakage currents, partial discharges, loss factors etc.

High current and short circuit tests are performed with voltages from 115 V to 697 V and currents with 150 kApeak and 100 kArms can be obtained. The maximum current at 6 kVrms is 2800 A.

Type testing of 115 kV cable accessories according to IEEE Standards 404 and 48 includes wet testing. The cable joint is wrapped in a water-tight envelope and subjected to high voltage and thermal cycling.
