Parameter Description
Ratio Current ratio error (in %) at the specified primary current (I
p
) and
burden.
Pol. OK: Polarity OK, phase angle is in the range of 0° ± 45°.
Failed: Wrong polarity of the CT or wrong polarity of the
measurement leads.
ε
C

operating burden.
This parameter is only displayed if the IEC 60044-1 standard is
selected in the CT-Object card.
Phase Phase displacement (in minutes) at the specified primary
current (I
p
) and burden.
N Winding turns ratio.
εt
Turns ratio error acc. to IEC 60044-6 class TPS or IEC 60044-1
class PX.
RCF Ratio correction factor.
This parameter is only displayed if the IEEE C57.13 standard is
selected in the CT-Object card.
