6.7.4 Ratio Table and Phase Table for IEC 60044-1, IEC 60044-6
and IEC 61869-2
To display the ratio table or the phase table, press the Ratio Table or
Phase Table soft key in the Ratio card.
If the selected standard is IEC 60044-1 , IEC 60044-6 or IEC 61869-2 , these
tables show the ratio error and the phase displacement
• for different current values between 1% and 200% of the rated current, and
• at 100%, 50%, 25% and 12.5% of the
operating burden defined in the
CT-Object card ("Burden" parameter), and
• at 100%, 50%, 25% and 12.5% of the nominal burden defined in the
CT-Object card ("VA" parameter) or at 1VA if one of these percentages
results in a nominal burden smaller than 1VA.
Use the Results with Op. Burden or Results with Nom. Burden soft key to
display the results related to the operating burden ("Burden" parameter in the
CT-Object card) or related to the nominal burden ("VA" parameter in the
CT-Object card).
The ratio table and the phase table contain all measurement points defined in
the standards IEC 60044-1, IEC 60044-6 and IEC 61869-2.
Use the cursor keys to scroll through the table columns (1% of rated
current to 200% of rated current).
