The ground current
I
N
is either measured directly or calculated from the conductor cur-
rents:
In addition, the following may be available:
•
Θ/Θ
Trip
thermal measured value
of overload protection value for stator in % of the
trip initiating overtemperature
•
Θ/Θ
LTrip
thermal measured value
of restart inhibit (rotor winding)
•
Θ
Restart
restarting limit
of restart inhibit
• T
Reclose
total time
, before the motor can be restarted
•
Θ

temperature values
at the RTD-boxes.
The power and operating values upon delivery are set such that power in line direction
is positive. Active components in line direction and inductive reactive components in
line direction are also positive. The same applies to the power factor cos
ϕ
. It is occa-
sionally desired to define the power draw from the line (e.g. as seen from the consum-
er) positively. Parameter
1108
P,Q sign
allows the signs for these componenets to
be inverted.
The calculation of the operational measured values is also performed during a fault.
The values are updated in intervals of > 0.3 s and < 1 s.
2.23.4.2 Transfer of Measured Values
Measured values can be transferred via the interfaces to a central control and storage
unit.
2.23.4.3 Information List
