How do I know if a transformer is saturated?
I am doing the simulation of the saturation of a
transformer, but what parameter tells me when a transformer
is saturated? How do you calculate? is on the plate?, there
is a rule that can help me? How could model? I understand
the saturation occurs when the flow can no longer bind to
the other winding, this is given to certain current, this
current is the same that appears as the highest in the bale
of features?
Thank you for your help

Answer / gunasekaran
if transformer getting saturation we cannot get magnetic
balace and it draw more magnetising current.if u applie 50%
rrated voltage saturation may be released. if u applie dc
current more than 10% of the magnetising current
transformer may be saturated that is y we r appilie less
current at the time of winding resistance. another one
method if u have sfra test kit u can find it out

Ask for manufacturers' test reports in which saturation
current of the CT is made available.For CTs with primary
winding you apply small voltage using step down transformer
and variable auto-transformer and measure the saturation
current when the secondary current ceases to increase and
then applying the ratio.For ring type, you have to boost
the current in the cable.Saturation current is usually
higher than the rated current
