HVDC test center


HVDC system:

Single mode: +/- 1.2 MV at 75 mA continuous current

Parallel mode: two system towers connected in parallel +/- 800 kV at 150 mA continuous current

Bipolar mode: two towers, each with opposite polarity +-/800 kV at 75 mA continuous current

 

Bushing:

1000 kV DC

 

Pulse Generator:

Lightning impulse voltages (LI): +/- 3.6 MV (1.2 μs/ 50 μs)

Switching impulse voltages (SI): + 1.7 MV/ -2.6 MV (250 μs/ 2500 μs)

Very Slow Front Overvoltages (VSFO): +/-600 kV (250 μs/ 50 ms; 5 ms/ 80 ms)

Superimposed pulse voltage tests (DC+ LI/SI/VSFO) for cable tests of cables with nominal voltages up to 640 kV
