Application

Among with the analog data, the binary data can also be exchanged with the line
differential protection relays. The usage of the binary data is application specific 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 protection relay's input
interface and is then available for the protection relay configuration. The circuit breaker
position indication is connected to the first input of BST 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 BST. This
way the information can be exchanged.
