Interposing Current Transformer II Adequacy

[YERUK123]

Hi,

While using Interposing Current Transformer , should we have to check the adequacy like that of Main Current Transformer

Ex: Main CT is 600/1A, Class: PX, Vk: 300V and Imag : 30mA @ Vk

If 300V is suitable for the Requirement wrt Main CT.

Interposing CT is 600/1/1A , Should we check the adequcy here too ??

would appreciate your response.

Thanks and Best Regards,
Yeruk

Yeruk,
Any equipment needs to be sized before you can prepare procurement specifications.
If you are using the existing equipment and want to be sure you need to repeat the sizing calculation to assure that the existing equipment parameters are adequate for the intended duty.
This applies to the interposing CT and the main CT in this case.
Your post doesn't provide much information and hence it is difficult to be any more direct.
Hope this is helpful.
