So far wiAutoLink process an Fault condition and waits an opening of the upstream recloser or
breaker.
At the occurrence of zero current, the sectionalizer registers the first count and show information
“Dead line condition”
3.
If the upstream recloser or breaker closes and no further fault detected, could be considered an
temporary fault condition, within the memory resetting time.
The wiAutoLink will timeout reset its counter and return to the monitor mode. So far,
wiAutoLink register
”Device returned to normal condition”
Figure 38.
D.2.2.
Operating Under Permanent Fault Conditions
The remaining 10-20% of faults in distribution overhead lines considered permanent. During these faults,
the continuous cycling of the recloser does not clear the fault.
The wiAutoLink will pick up, measure zero current and count, reaching its trip count setting.
The wiAutoLink will trip on the last open cycle of the recloser, isolating the permanent fault in its branch
and allowing the recloser to close prior to going to lockout and maintain power to the unaffected branches.
D.2.2.1.
Operating Under Permanent Fault Conditions with Trip two count setting Recloser.
1.
The wiAutoLink is in monitor mode under normal load conditions.
wiAutoLink register
“Device returned to normal condition”
if last overhead has been solved
without trip or
“The device has been normally powered up”
if is the first time that wiAutoLink
has powered.
2.
When a fault is present the wiAutoLink senses a current above a programmed pickup threshold
(Ia wiAutoLink) and becomes active.
So far, wiAutoLink process a Fault condition and waits an opening of the upstream recloser or
breaker.
At the occurrence of zero current, the sectionalizer registers the first count and show information
“Dead line condition”
