ABB RET670 - Setting Parameters

Setting of timers for distance protection zones
The required time delays for different distance protection zones are independent of
each other . Distance protection zone 1 can also have a time delay, if so required for
selectivity reasons. Time delays for all zones can be set in a range of 0 to 60 seconds.
The tripping function of each particular zone can be inhibited by setting the
corresponding Operation parameter to Disabled. Different time delays are possible for
the phase-to-ground tLG and for the phase-to-phase tPP measuring loops in each
distance protection zone separately, to further increase the total flexibility of a distance
protection.
3.6.1.4 Setting parameters
Signals and settings for ZMQPDIS are valid for zone 1 while signals
and settings for ZMQAPDIS are valid for zone 2 - 5
