Mode of Operation
The current metering trans-
former is connected to the
current control relays H 475
as follows:
ductor through the hole sever-
al times makes it possible to
meter currents below the no-
minal range.
Red core to term. 5

- U1.
- U2.
- U3.
The metered conductor is
drawn through the central
hole of the current metering
transformer. Drawing the con-
If the conductor is drawn
through the central hole e.g. 5
times, the metering trans-
former will register 50 A when
the current in the conductor is
10 A.
In amplitude and phase the
output voltage is proportional
to the phase current metered.
