The below links belongs to Public organizations stating what their take for DCCT is:

Yes - but that needs to be specificall called a DCCT - it is not just a plain "CT".
It is a device that has a sepatate excitation coil, and measures DC indirectly by its effect on the saturation of the core.

And this, in turn, is entirely different from a Hall-effect based sensor.

Again, if you just say "CT", then that has to mean that a basic Current Transformer will do the job.
If either a DCCT or a Hall-effect device is required - as in this case - then you must specifically say so.
Just saying "CT" is likely to be misleading.

It should have been mentioned DC CT instead !
you just invented the DC transformer, patent it immediately. You will be one of the worlds richest people. Erik


So your explanation might be helpful for him as he doesnt seems to know/account about the abbrevation DCCT and its existance as he offers me to get this patented . Its upto OP to use what technology as per his/her requirements , you are reasonable to me as atleast you consider the existance of DCCT .

True Transformer and False Transformer is not the part of discussion but Abbreviations.


Andy Neil said:

Wrong.

The term "transformer" specifically means an inductively-coupled device - so calling a Hall-effect device a "transfomer" is plain wrong.
It's not just an abbreviation, it's wrong.


FALSE !! if it has to mean inductively coupled device it has to be called ' ELECTRICAL TRANSFORMER' and not as you simply call it a 'TRANSFORMER' . Transformer has various meanings google could show you.
