Description
1.1
Features
The PACT Analog current transformers form a complete
range of bus-bar, plug-in and winding current transformers
for measuring AC currents with a range of 1 A to 4000 A.
Current transformers belong to a group of specialized
transformers and are used in those areas where currents
cannot be measured directly. Depending on the
transformation ratio, the primary current is transmitted to a
smaller electrically isolated secondary current.
PACT Analog current transformers can be used either as an

–
Safe isolation as a result of the test voltage of 12 kV
(1.2/50 μs) prevents a hazardous operating voltage
from being transferred to downstream components
Conforms to surge voltage category 3 as a result of the
test voltage amplitude
Routine test according to EN 50178

isolation"; see page 28.
industrial version or as a transformer that can be officially
calibrated.
The calibration process involves additional costs,
which are specified in accordance with the
national table of fees.
PACT Analog current transformers are available in the
following designs:
– Winding current transformer (I pn : 1 A to 40 A)
– Bus-bar current transformer (I pn : 50 A to 500 A)
– Plug-in current transformer (I pn : 50 A to 4000 A)
WARNING: Danger due to damaged current transformers
?
?
?
Before startup, check that the housing of the current transformer is not damaged.
Also before startup, check that there are no electrically conductive connections between the primary
conductor and the secondary terminals.
If a built-in current transformer is removed in order to be used in a different system, check the current
transformer for damage again.
WARNING: Danger due to voltage at open circuit
The output of the current transformer is a constant current source. In the event of an increasing load, the output
voltage thus increases and reaches its maximum at infinite load (i.e., with open secondary terminals).
?
?
?
Avoid open-circuit operation at all costs.
Note that unloaded transformers must be short circuited.
Only start up the current transformer once the secondary cables are connected on both sides.
