Description
Distance protection: Distance protection - 1 phase and 3 phase zone extension signal missing
The zone extension is activated by the status of the autorecloser and the status of the teleprotection: if the autorecloser is in service and the teleprotection is out of service we extend the Z1 from 80% of the line to 100% of the line in order to trip on all faults on the full line is base time.
