PT = external potential transformer ratio
CT, CT Primary Current = primary current rating of external current transformer
FSU = voltage full scale
FSI = current full scale
U1 = voltage fundamental
I1 = current fundamental
@ 10% to 120% of voltage FS and 2% to 120% of current FS Higher resolution is achievable via communications
Where the current is
>
10% FS, the energy accuracy is better than 1.5% Rdg.
Additional Notes
1. Accuracy is expressed as
±
(percentage of reading + percentage of full scale)
±
1 digit. This does not include inaccuracies introduced
by the user's potential and current transformers.
2. Specifications assume: voltage and current wave forms with THD
≤
5% for kvar, kVA and PF; reference operating temperature: 20 - 26
°
C.
3. Ordinary measurement error is considerably less than the specified accuracy which indicates maximum error.
