Abstract
A device for shutoff protection of the electric main comprises a differential current transformer, a magnetic core of which encloses conductors for power supply of the protected electric main, to the secondary winding of which OR element is connected, to the said element an automatic break system is connected, three another current transformers have magnetic cores which separately enclose every phase power conductor of the protected electric main, the device also comprises an automatic break system connected with them via amplifiers, a high-frequency filter, a detection and selection device and OR element. The device is additionally provided with an autodiscrimination unit of high-frequency signals, which is connected between the detection and selection device and OR element and connected to the automatic break system.
