ΔI
In order to prevent faulty
tripping of phase
selective protection
functions that use the
current as tripping
criterion. If the difference
of the measured earth
current and the
calculated value I0 is
higher than the pick up
value ΔI, an alarm event
is generated after
expiring of the excitation
time. In such a case, a
fuse failure, a broken
wire or a faulty
measuring circuit can be
assumed.

Kd
Dynamic correction factor
for the evaluation of the
difference between
calculated and measured
earth current. This
correction factor allows
transformer faults,
caused by higher
currents, to be
compensated.
