Cyclic Control of Protective Functions via Automatic Reclosure
Addresses 7200 to 7211 as well as 7248 and 7249 allow cyclic control of the various protection functions by
the automatic reclosing function. Protection elements can thus be blocked selectively, made to operate instan-
taneously or according to the configured delay times. The following options are available:
The following options are available:
• Set value T=T; The protection element is delayed as configured, i.e. the automatic reclosing function
does not effect the element;
instant. T=0 The protection element becomes instantaneous if the automatic reclosing function is ready
to perform the mentioned cycle;
blocked T=∞ The protection element is blocked if the auto-reclose function reaches the cycle defined in
the parameter. The element picks up, however, time expiry of the element is blocked by this setting.
Dead Times (2nd to 4th AR)
If more than one reclosing cycle was set, you can now configure the individual reclosing settings for the 2nd to
4th cycle. The same options are available as for the first cycle.
For the 2nd cycle:
Address 7129
Address 7130
Addresses 7212 to 7223
and 7250, 7251
For the 3rd cycle:
Address 7131
Address 7132
Addresses 7224 to 7235
and 7252, 7253
For the 4th cycle:
Address 7133
Address 7134
Addresses 7236 to 7247
and 7254, 7255
Fifth to Ninth Reclosing Attempt
If more than four cycles are configured, the dead times set for the fourth cycle also apply to the fifth through to
ninth cycle.
Blocking Three-Phase Faults
Regardless of which reclosing program is executed, automatic reclosing can be blocked for trips following
three-phase faults (address 7165 3Pol.PICKUP BLK). The pickup of all three phases for a specific overcur-
rent element is the criterion required.
