1. It is the % RD error for the maximum phase voltage/phase current in the three phases because it is the residual value
calculated from the phase voltage/phase current.
2. Split-core three[single]-phase power measuring modules support
±
0.5% RD accuracy for current. And these split-core
modules can increase the maximum ± 1% error depending on the penetration position of power cable.
3. Split-core single-phase single-hole power measuring module meets current accuracy ± 0.2% RD error and power/energy
accuracy IEC62053-22 Class 0.2S.
