Key:
PT = external potential transformer ratio CT, CT Primary Current = primary current rating of external current transformer
FSU = voltage full scale FSI = current full scale U
1
= voltage fundamental I
1
= current fundamental
 @ 80% to 120% of voltage FS and 1% to 200% of current FS
 @ 10% to < 80% of voltage FS and 1% to 200% of current FS
 Higher resolution is achievable via communications
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. Measurement error is typically less than the maximum error indicated here.
