Appendix: Technical Specifications 40
Key: PT - external potential transformer ratio c @ 80% to 120% of voltage FS and 1% to 200% of
current FS
CT - primary current rating of external current transformer
FSV - voltage full scale; FSI - current full scale
Vf- fundamental voltage; If - fundamental current
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. Accuracy calculated at 1 second average.
2. Specifications assume: voltage and current waveforms with THD ≤ 5% for kvar, kVA and PF; reference operating
temperature: 20 °C - 26°C.
3. Measurement error is typically less than the maximum error indicated here.
