Current Transformer
Current Transformer
(OP)
Hi,
May I know if a current transformer can be overloaded?
Let say I have a 100/5A CT and continuous current at primary varies from 140 to 210Amps,
Is there a possible that this CT will fail due to overloading?
Thank you and hoping any reply.

Thank you for the reply,
but how can I identify the CT TRF for the attached CT Specs?

RE: Current Transformer
permissible in order to maintain the protection class error [ALF] it is 10 times the rated[1000 A] and the metering accuracy factor [SF]=5 -class 0.2.
rated output is 10 VA for 0.2 class and 15 VA for 0.5 class.
See for more information- for instance:

RE: Current Transformer
How about the max permissible continuous current ?
Thank you.
