and can vary in each separate case. The demands for the speed of the binary signals
vary depending on the usage of the data. When the binary data is used as blocking
signals for the line differential protection, the transfer response is extremely high.
Binary signal interchange can be used in applications such as:
• Remote position indications
• Inter-tripping of the circuit breakers on both line ends
• Blocking of the line differential protection during transformer inrush or current
circuit supervision failure
• Protection schemes; blocking or permissive
• Remote alarming.
The figure shows the overall chain to transfer binary data in an example
application. The position indication of the local circuit breaker is connected to the
IED’s input interface and is then available for the IED configuration. The circuit
breaker position indication is connected to the first input of BSTGGIO which is
used to send information to the remote end via communication. In the remote end,
this information is handled as a remote circuit breaker open position and it is
available from the first output of BSTGGIO. This way the information can be
exchanged.
