摘要： A current limiter used for stable control of an electric power system, and particularly applied to a high voltage of the electric power system, has a reduced voltage for suppressing the overcurrent of the electric power system. The current limiter is not enlarged so that the current limiter secures the insulation of the voltage withstanding level, and the current limiter is easy to be introduced to the system. A limiting device is inserted between a low potential terminal of a winding of a star-connection of a three-phase transformer that has at least one winding of the star-connection and a ground point.

摘要： A plurality of solid-state switches are provided in parallel with a main circuit switch. A main circuit current is detected by a first current detecting device. A current flowing in each of the plurality of solid-state switches is detected by a second current detecting device. Based on the detected currents of the first and second current detecting devices, the main circuit switch is commanded to open and each solid-state switch is commanded to close by a control circuit, when a fault is detected by a fault detecting circuit. At this point of the process when the main circuit switch is opened, when a commutation anomaly is detected by a commutation detecting circuit, the conducting status of each solid-state switch is maintained. When the commutation achieves a normal status, each solid-state switch is interrupted and circuit breaking, at the point the capability of each solid-state switch is exceeded, is prevented.

摘要： A gas insulated switching apparatus has lightning arrestors in a line side unit. Each lightning arrestor is mounted to be moved linearly into and out of connection with a corresponding conductor. Specifically, the cover which supports the lightning arrestor is disposed beneath the bottom plate of the vessel of the line side unit. The lightning arrestors are connected to a monitor of an operating device beneath the line side unit. Since the lower portion of the lightning arrestors are connected to the monitor, the length of the connection lines is made sufficiently short.
