Application manual
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 Off. Different time delays are
possible for the ph-E (tPE) measuring loops in each distance protection zone
separately, to further increase the total flexibility of a distance protection.
