FIELD: electricity.
SUBSTANCE: device for protecting pipelines from geomagnetically induced ground currents is located, consisting of a protector, an electrical conductor, a relay, a control unit, a current source and a magnetic field strength meter, an electric circuit is used to connect the protector to the pipeline through a relay, the Earth's magnetic field strength is measured, and when a certain threshold level of the Earth's magnetic field parameters is reached, the protector band is closed by the relay contacts, when the field parameters are lower than the threshold - the protector band is opened.
EFFECT: increased level of protection of pipelines subject to the influence of geomagnetically induced ground currents.
