This block is suitable for distance protection, line differential, transformer differential,
over-current and ground-fault protection functions.
• Autorecloser indications in monitor direction
Function block with defined functions for autorecloser indications in monitor direction,
I103AR. This block includes the FUNCTION TYPE parameter, and the INFORMATION
NUMBER parameter is defined for each output signal.
Measurands
The measurands can be included as type 3.1, 3.2, 3.3, 3.4 and type 9 according to the
standard.
• Measurands in public range
Function block that reports all valid measuring types depending on connected signals,
I103Meas.
• Measurands in private range
Function blocks with user defined input measurands in monitor direction, I103MeasUsr.
These function blocks include the FUNCTION TYPE parameter for each block in the
private range, and the INFORMATION NUMBER parameter for each block.
Fault location
The fault location is expressed in reactive ohms. In relation to the line length in reactive
ohms, it gives the distance to the fault in percent. The data is available and reported when
the fault locator function is included in the IED.
Disturbance recordings
• The transfer functionality is based on the Disturbance recorder function. The analog
and binary signals recorded will be reported to the master by polling. The eight last
disturbances that are recorded are available for transfer to the master. A file that has
been transferred and acknowledged by the master cannot be transferred again.
• The binary signals that are included in the disturbance recorder are those that are
connected to the disturbance function blocks B1RBDR to B22RBDR. These function
blocks include the function type and the information number for each signal. For
more information on the description of the Disturbance report in the Technical
reference manual. The analog channels, that are reported, are those connected to the
disturbance function blocks A1RADR to A4RADR. The eight first ones belong to the
public range and the remaining ones to the private range.
