Presentation of standard configurations

Functional diagrams
The functional diagrams describe the IED's functionality from the protection,
measuring, condition monitoring, disturbance recording, control and interlocking
perspective. Diagrams show the default functionality with simple symbol logics
forming principle diagrams. The external connections to primary devices are also
shown, stating the default connections to measuring transformers. The positive
measuring direction of directional protection functions is towards the outgoing feeder.
The functional diagrams are divided into sections which each constitute one
functional entity. The external connections are also divided into sections. Only the
relevant connections for a particular functional entity are presented in each section.
Protection function blocks are part of the functional diagram. They are identified
based on their IEC 61850 name but the IEC based symbol and the ANSI function
number are also included. Some function blocks, such as PHHPTOC, are used
several times in the configuration. To separate the blocks from each other, the IEC
61850 name, IEC symbol and ANSI function number are appended with a running
number, that is an instance number, from one upwards. If the block has no suffix
after the IEC or ANSI symbol, the function block has been used, that is,
instantiated, only once. The IED's internal functionality and the external
connections are separated with a dashed line presenting the IED's physical casing.
Signal Matrix
With Signal Matrix the user can modify the standard configuration according to the
actual needs. The IED is delivered from the factory with default connections
described in the functional diagrams for BI's, BO's, function to function
connections and alarm LEDs. Signal Matrix has a number of different page views,
designated as follows:
• Binary input
• Binary output
• Functions
