The mechanisms of exposure of quasi -constant geo -induced currents on electrical networks

The influence of geomagnetic disturbances on the operation of electric networks and their elements is considered. The analysis of the sources of occurrence and the spread of quasi -preserved geo -induced currents is given, their impact on power transformers has been comprehensively investigated. Computer modeling of unilateral saturation of power transformers was made. A geoelectric hypothesis of the emergence and development of the accident at the Sayano-Shushenskaya hydroelectric power station is proposed.
For scientific and engineering and technical workers engaged in the operation and design of electrical stations, substations and networks, as well as graduate students and undergraduates of electric power and electrical specialties
