1. Трансформатор тока нулево последовательности шннного тина с пр моугольным магннтонроводом, предназначенный дл  запи1ты генераторов , отличающийс  тем, что дл  уменьшени  токов небаланса шины, представл ющие собой первичную обмотку, расиолагаютс  вдоль малой оси магнитопровода, а вторична  обмотка, разделенна  на две части, расиолагаетс  на малых сторонах магнитонровода.1. The current transformer of a zero-voltage string with a rectangular magnet conductor, designed to record generators, characterized in that to reduce the unbalance currents of the bus, which are the primary winding, are distributed along the small axis of the magnetic circuit, and the secondary winding, divided into two parts, divides on the small sides of the magnetonrovod.

2. Трансформатор тока по н. 1, отличающийс  тем, что дл  обеспечени  селективности действи  зандиты на середине длинных сторон магнитопровода расположены две обмотки, соедннениые между собой встречно последовательно и включенные на блокировочное реле.2. Current transformer by n. 1, characterized in that, in order to ensure the selectivity of the sandwich action, two windings are located on the middle of the long sides of the magnetic circuit, connecting each other oppositely in series and connected to the locking relay.
