Studies of seismic stability of electro-technical facilities ORU-330 for Irganaisk HPP
12 illustrations, 6 references. There have been given the calculation results of six units (including VGU-330, disconnector RS31-330, current transformer TFRM-330, voltage transformer NKF-330, voltage limiter OPN-330, high-frequency rejector VZ-2000-1.0U) of electro-technical facilities ORU-330 kV for Irganaisk hydrosystem operating in the seismic region with 9 magnitudes by MSK-64 scale. The seismic stability was assessed and the measures to strength non-seismostable products were suggested.
