In the zero sequence voltage spectrum, the number of the greatest higher harmonic of zero sequence voltage exceeding the setpoint level for said harmonic is recorded. For each feeder, the phase shift thereof with respect to the harmonic of zero sequence voltage is recorded. The phase shifts enter the logic block which isolates the feeder wherefor the sign value at the phase angle is opposite with respect to the phase angles of other feeders.

Abstract: FIELD: information security. 
     SUBSTANCE: invention relates to the field of information security. To achieve the effect, when transmitting information packets from a source to a receiver, each information packet is assigned a sequence number and the time of arrival of each information packet to the receiver is recorded. The receiver determines for each packet transmitted during the transmission session, starting from the second, the difference between the time the receiver received this packet and the time the receiver received a packet with a sequence number one less. Based on the obtained difference, the receiver calculates the metric of each packet transmitted during the transmission session, starting from the second, and forms the transmission session metric as a result of the product of the metrics of each packet, starting from the second. In this case, if among the numbers of the received information packets, each number was met exactly once and the metric of the transmission session is not less than the value specified for the current transmission session, then the transmission of all information packets from this source to this receiver is considered successful, otherwise it is considered, that the transfer went wrong.
