Hello,
These values a completely normal because of the load. Under 20% of load we cannot guarantee any accuracy.
As example, when you look at the standard of the current transformer, for a 0,5 CT , the CEI says : class 0,5% is ok from 100% to 120% of the norminal current and accuracy is...
Hi,
You are right, regarding the IEC standard :
- if the energy (or the power) is positive, the load is in consumption (energy is going from the utility to the load)
- if the energy is negative (or the power), the load generates power (energy is going from the load to the utility)
For me it's...
