2.1.6.1 Description
The general protection data (P.System Data 2) include settings associated with all functions rather than a
specific protection or monitoring function. In contrast to the P.System Data 1 as discussed before, they can
be changed with the setting group.
Applications
When the primary reference voltage and the primary reference current of the protected object are set, the
device is able to calculate and output the operational measured value percentage.
For purposes of fault location, a maximum of three different line sections can be considered.
For utilization in motors, detection of the motor start represents an important feature. Exceeding a configured
current value serves as a criterion.
