18.1.7

Current transformer requirements for CTs according to

other standards

SEMOD53771-1 v1

M11623-4 v3

All kinds of conventional magnetic core CTs are possible to use with the IEDs if
they fulfill the requirements corresponding to the above specified expressed as the
rated equivalent limiting secondary e.m.f. E

al

according to the IEC 61869-2

standard. From different standards and available data for relaying applications it is
possible to approximately calculate a secondary e.m.f. of the CT comparable with
E

al

. By comparing this with the required rated equivalent limiting secondary e.m.f.

E

alreq

it is possible to judge if the CT fulfills the requirements. The requirements

according to some other standards are specified below.

18.1.7.1

Current transformers according to IEC 61869-2, class P, PR

M11623-6 v4

A CT according to IEC 61869-2 is specified by the secondary limiting e.m.f. E

ALF

.

The value of the E

ALF

is approximately equal to the corresponding E

al

. Therefore,

the CTs according to class P and PR must have a secondary limiting e.m.f. E

ALF

that fulfills the following:

18.1.7.2

Current transformers according to IEC 61869-2, class PX, PXR (and

old IEC 60044-6, class TPS and old British Standard, class X)

M11623-14 v5

CTs according to these classes are specified approximately in the same way by a
rated knee point e.m.f. E

for class X and the

limiting secondary voltage U

al

for TPS). The value of the E

knee

is lower than the

corresponding E

al

according to IEC 61869-2. It is not possible to give a general

relation between the E

knee

and the E

al

but normally the E

knee

is approximately 80 %

of the E

. Therefore, the CTs according to class PX, PXR, X and TPS must have a

18.1.7.3

Current transformers according to ANSI/IEEE

M11623-22 v6

Current transformers according to ANSI/IEEE are partly specified in different
ways. A rated secondary terminal voltage U

ANSI

is specified for a CT of class C.

U

ANSI

is the secondary terminal voltage the CT will deliver to a standard burden at

20 times rated secondary current without exceeding 10 % ratio correction. There
are a number of standardized U

ANSI

values for example, U

ANSI

is 400 V for a C400
