This paper describes the seismic isolation technique by using a pendulum type counterweight as an application for the large scale bushing. In the first part, the characteristics of the seismic isolation device were expressed with differential equation of 3-degrees of freedom model. We verified by using the scale model that the simple simulation model is competent for expression of the vibration characteristics of proposed device. In the next place, using point P, Q theory for the simulation model, we proposed the determination method of the optimized parameter consist of seismic isolation device using a pendulum type counterweight. At last the effect of optimized isolation device was investigated with actual model. Sufficient suppression has been achieved by this proposed optimization method, consequently this seismic isolation device has a prominent potential to apply for large scale electric power devices.
