Zusammenfassung:	FIELD: power supply systems for flying vehicles. ^ SUBSTANCE: proposed method for checking and protecting power lines depends on comparison of desired value of rated current with actual value and separation of difference in excess of rated current; excess current is obtained by differentiating actual current from its rated value. Proposed device implementing this method has final element built around field-effect transistor, sensing element built around low-value resistor, multiplex communication microcontroller, control unit, comparison unit, voltage switch, control signal generating unit, and differentiating unit. As an alternative, double-operation thyristor can be used as final element and current transformer, as sensing element. ^ EFFECT: remote control capability, enhanced speed and reliability. ^ 3 cl, 2 dwg
