Asid, I am familiar with 0.2 and 0.2G. Does this help? If so, the the classification reveals the error limits for a specific multiple of rated current. For example, 0.2 means the error ratio is limited to +/- 0.2% when carrying 1.2xRated A. For 0.2G, the error ratio is limited to +/- 0.2% when carrying 1.0xRated A.

Dear Phil,

Thanks for your input. Do you have any good site related to current transformer? Because I searched it on the net but I did not get a specific site.

Waiting for your reply...

Asif, if you are dealing with a German manufacturer, the standard is VDE 0414!

Dear Asif,

It's more stringent than 0.2 class of accuracy used by australian standard.
