The invention proposes the current transformer of zero string at the voltage of 6-35 kV, the active part of which consists of a magnetic conductor, the primary winding having three tires and the secondary winding. The secondary winding is single-turn and short-circuited. It serves as the primary winding for two single-turn current transformers having secondary windings. To one of the secondary winding it is connected analog -to- digital converter, to the secondary one -analog relay protection. Magnetic conductors of all current transformers are made of nanocrystal alloy having high magnetic conductivity.
