In view of the increasing global market for high voltage (HV) vacuum circuit breakers in the voltage rating ≥ 72.5 kV, it is necessary to focus our attention on developing the vacuum interrupters (VIs) for these ratings. VCBs have already penetrated the 72.5 kV market and trials are progressing with introducing up to 145 kV VIs into the power networks. Prototype of the 252 kV VI has already been demonstrated.
Electricity networks of the future are moving towards supergrid networks. These networks will use HVDC voltage to supply center of consumption from sources that are far from them or to connect different countries together. The objective is to ensure network stability and security, especially with contribution renewable energies like large offshore wind farms and solar plants.
