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 zone1 can also have a time delay, if so required for
selectivity reasons. One can set the time delays for all zones (basic and optional) 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 ph-E (tPG) and for the ph-ph (tPP) measuring loops in each
distance protection zone separately, to further increase the total flexibility of a distance
protection.
3.6.2.3 Setting parameters
Settings for ZMCPDIS (21) are valid for zone 1, while settings for
ZMCAPDIS (21) are valid for zone 2 - 5
