Hybrid HVDC breaker - Enabling the DC grids of the future

​Hitachi Energy's Hybrid HVDC breaker removes a significant technical challenge in the development of HVDC grids, which has been a limitation for high voltage DC technology expansion. It permits the transmission system to maintain power flow if there is a fault on one of the lines; the breaker isolates the fault by breaking the direct current, even if extremely high-power levels are required.

​Earlier deployment of HVDC has led to an increasing number of point to point connections, and some multi-terminal systems, in different parts of the world. The logical next step is to connect the power lines and optimize the reliability of the network, a DC grid, which will also enable the balancing of loads, integration of large amounts of renewables, lowering of transmission losses and facilitate energy trading across borders. A DC grid would support and stabilize the AC grid by working as power superhighways, avoiding black outs and minimizing power losses.

​Join us to learn more about how the Hybrid HVDC Breaker from Hitachi Energy can help to shape the DC grids of the future and increase access to reliable and affordable energy for all.
