CTSR Series
Primary nominal residual current and primary nominal current
The primary nominal residual current is the sum of the instantaneous values of all currents flowing through the aperture of the
transducer.
The primary nominal current is the current flowing through any conductor placed into the aperture of the transducer.
The presence of a primary nominal current DC or AC leads to an additional uncertainty.
For example, with a primary nominal current of 30 A the uncertainty referred to primary is typical 4.3 mA.
CTSR transducer in Test mode
When the V ref pin is forced at a low level voltage between 0 and 1 V and is maintained at this level, the output voltage V out of CTSR
transducer exhibits a fixed value (see specification) as if it measured a primary test current.
The activation time of test mode is min 30 ms. The CTSR transducer can be maintained in test mode as long as needed for
checking that it is fully operating.
CTSR transducer in Degauss mode
The CTSR transducers go in degauss mode automatically at each power on or on demand by using the V ref pin.
At power on:
A degauss is automatically generated at each power on of the CTSR transducer; during degaussing the output voltage V out is
maintained at 0.3 V typ. (max 0.5 V). After c.a. 110 ms, the output voltage V out is released and takes the normal operation level in
relation with the measured primary current.
Using V ref pin:
When the pin V ref is released from the Low level voltage defined in the Test mode above, there is a rising edge on V ref which
generates an automatic degauss.
The activation of degauss takes typically 40 μs after releasing V ref pin, then degauss lasts typically 110 ms.

Isolation around the CTSR transducer housing
Due to the joint between the case and the cover of the CTSR transducer, there is some isolation distance to respect when primary
conductors pass around the CTSR housing.
The figure below shows the joint and the apertures where the clearance between the secondary part inside the CTSR transducer
and the surface of the housing is 3 mm (label E).
