Recent tendencies of installation surroundings and progress of technologies for environment load reduction on high voltage circuit breakers are reviewed. Damage situations of the circuit breakers on the Great East Japan Earthquake in 2011 are shown and studies of seismic design and guidelines of substation equipment are reviewed. In addition, new surroundings such as an offshore substations for wind farms are introduced. Life extension technologies with RCM (Reliability Centered Maintenance) will be more important technologies for a point of view of environment load reductions. The transition from fundamental phase to industrial phase will be made in research and development of substitute SF6 GCB (Gas Circuit Breaker).
