_______________
For supervision of run time, breaker fault and auxiliary voltage
Ino – Normalized nominal current related to base current transformer (current transformer with
highest transformation ratio)
IN – Nominal current of bay current transformer
Two fault record buffers, each 300 ms(200 ms before and 100 ms after the fault) are available.
Release auto: The fault record is automatically switched over to the other memory after each
end of a fault. A previous fault record, still existing there, is overwritten.
Release manual: After storing two fault records, the fault recording function remains blocked
until released via operation in DA 8300. If released, then both buffers are erased, independent
of their contents.
