Compact gas-insulated highvoltage switchgear has been
available for AC solutions for a few
decades. But because controlling
a DC electrical field is extremely
tricky, it hasn’t yet been possible

systems for DC applications.
Now Siemens has managed to
develop an insulator that can
withstand the stress induced by
high-voltage DC.
