Hello , I would like to ask one question. Current transformers has one of the major component in electricity but we know that per load level, VA, temperature ext accuracy of these transformers can change. CT manufacturers gives accuracy diagrams for different load levels from %5 load to full load. But what is happening when the load level is lower than %5. For example if you have 4000/5 current transformer to measure current and if you have load that can go down for sometime to 50A in primary, is it possible that you can have 0.00mA in secondary?
Some CT manufacturers written specs as <%5 zone unstable zone, where there is no value for accuracy or there is no warranty that CT's are working probably. Is there any technical study that investigate <%5 load conditions?
