DIFF
Bug fixing:
●
In versions ‑606 to ‑610 inrush signaling from all
three measuring systems was suppressed when
harmonic blocking in measuring system 1 was
triggered. This was not accompanied by tripping.
Nevertheless there was the possibility of an
overreaction (tripping) when an inrush condition
was not recognized by one measuring system
with the operating mode set to “Not phase-
selective” and in an other measuring system the
second harmonic component reached a value of
approximately between 70% and 130% of the
fundamental.
FT_DA
Bug fixing:
●
The fault data for FT_DA: Fault curr.IY,b p.u.
(026 088) were mistakenly calculated on the
basis of current I
Y,a
.

Bug fixing:
●
If communication was interrupted during control
access via the Ethernet interface using the
operating program MiCOM S1, renewed control
access was only possible after a warm restart of
the P634.
●
Previously a break in the client-server
communications link could occur after
approximately 49 days for about 20 minutes.
GOOSE and GSSE are not affected.
