要約(英語): Electric Technology Research Association (ETRA) of Japan had carried out investigations on disturbances of digital control circuits in generator stations and substations experienced by all the Japanese utilities for 10 years from 1990. The total number of the disturbances is 330. This paper summarizes the disturbances experienced in Japan. It is observed in the table (a) that one third of the disturbances out of 330 cases are for protection equipment, one quarter for tele-control equipment and the other quarter for control equipment. (b) shows that two thirds of the disturbances are caused by lightning surges, one sixth by switching surges in main circuits (high-voltage side) and one twelfth by switching surges in dc circuits which are a part of control circuits (low-voltage side). _x000D_ Field test results of very fast transients (VFTs), mostly caused by switching surges in a gas-insulated substation (GIS), are summarized considering electromagnetic disturbances in GIS control circuits which occasionally result in power system operation failures.
