FIELD: radio engineering, communication.
SUBSTANCE: invention proposes the use of transparent transmission of teleprotection commands in the form of GOOSE or GSSE messages between substations, combined with channel supervision and monitoring (CSM) equivalent to CSM offered by conventional teleprotection equipment. To this end, the method includes exchanging CSM messages between two substations through an inter-substation channel in periods where no command messages are transmitted from the first to the second substation; and evaluating the CSM messages in terms of the suitability of said inter-substation channel.
EFFECT: broader functional capabilities.
