More Information
Summary:There is described a method for reception of protection commands in a remote tripping device, in which signals are received, protection commands and combinations thereof are coded in an individual signal or a combination of signals, and each protection command is allocated a minimum security value. Each signal is allocated a detector which detects the presence of the signal based on at least two different security threshold values. A protection command is detected if an individual signal is detected with a security threshold value which is greater than or equal to the minimum security value allocated to that protection command, or if all the signals in the combination of signals which codes the protection command individually or in conjunction with other protection commands are in each detected with a security threshold value which is greater than or equal to the minimum security value allocated to the protection command.
