HVDC Disconnectors
Disconnectors (DSC) for HVDC applications are designed to specific constraints and requirements typical for DC applications, that are quite different compared to AC applications. They are requested to withstand DC voltage open gap and to ground to ensure safety for the people in the substation and to permit proper and safe layout configuration. In some cases, like for filter applications, they are requested to break a sum of harmonic currents at a certain voltage (amply smaller than the rated voltage of the disconnector) due to the ripple created by harmonics on the reactances.

Today’s Challenging Environment
Globally the utility environment is becoming more complex and utilities are having to manage new challenges such as:
- Increasing demand for electricity
- Connection of remote generation
- Growth of distant offshore wind
- Integration of variable renewable generation
- Need for security of supply
- Reduce carbon footprint
- Land costs becoming more expensive
- New right-of-way access permits increasing difficult to obtain
The only choice for many utilities is to restructure their grid systems to manage these challenges. Utilities are looking for cost effective solutions to transfer power and to improve the quality, stability and reliability of the grid which will anticipate their needs for the next 20 to 50 years.
GE Vernova's Solution
High Voltage Direct Current (HVDC) solutions are ideal for supporting existing AC transmission systems or for building new power highways. HVDC is a system which interconnects two AC networks, converting AC voltage to DC voltage, and DC voltage to AC voltage utilizing power electronics technology. HVDC systems enable transfer of power, interconnection of grids, integration of renewables and maximize grid performance.

Knee Type Disconnector up to 800 kV
GE Vernova’s knee type disconnector SPO/SPOL has been designed with one rotating and two fixed insulators. Thanks to its folding arm design (knee), it requires limited overhead clearance and a very short phase-to-phase distance. The outstanding gap factor allows a relatively short air gap and a lighter arm. No electrodes are needed in the middle.
The center of gravity is quite low, with great advantages for balancing, seismic withstand and operating torque. The low operating torque permits sure operation using a motor drive mechanism as well as easy manual operation and it does not stress the rotating insulator. The design is contact rebound free resulting in very smooth movement and a relatively fast operation (about 10÷15 s for a 550 kV disconnector).
L-Contact
The main contact can be of the L- type, the solution patented by GE Vernova helping to ensure highest protection against air pollution and ice. The L-Contact is also maintenance free and therefore represents the best technical choice for DC applications.
Center Break Disconnector up to 245 kV
The center break disconnector type S2DA is the most commonly used and economical disconnector, but requires an increased phaseto-phase distance. In the center break design the two arms rotate and the disconnector opens in the center.
Vertical Break Disconnector up to 800 kV
The vertical break disconnector has one rotating and two fixed insulators. The double movement of the blade ensures excellent performance in terms of ice breaking and short-circuit withstand. The vertical break requires a minimal phase-to-phase distance and the main contact can be of the L-type.
