4.2.3.10 Technical revision history
Table 212: INTRPTEF Technical revision history
Technical revision Change
B Minimum and default values changed to 40 ms for
the Operate delay time setting
C The
Minimum operate current setting is added.
Correction in IEC 61850 mapping: DO BlkEF
renamed to InhEF. Minimum value changed from
0.01 to 0.10 (default changed from 0.01 to 0.20) for
the
Voltage start value setting. Minimum value
changed from 0 ms to 40 ms for the
Reset delay
time setting.
D Voltage start value description changed from
"Voltage start value for transient EF" to "Voltage
start value" since the start value is effective in both
operation modes. Added support for calculated
Uo. Uo source (measured/calculated) can be
selected with "Uo signal Sel". Voltage start value
setting minimum changed from 0.10 to 0.05.
E Min operate current setting scaling corrected to
RMS level from peak level.
