| Summary: | Modern trends in relay protection (RP) based on the substitution of
electromechanical protection relays (EMPR) by digital protective relays
(DPR) have resulted in the emergence of an absolutely new problem, which was
not known before. This problem is the possibility of an intentional remote
destructive impact (IRDI) on relay protection in order to put it out of
action or make it perform functions that have nothing to do with the current
operational mode of protected electric equipment. Traditional and well-known
methods ensuring information safety cannot fully prevent unauthorized
actions of RP. The article describes a new way for the problem solution. |
