Coupling 3EM-400 with CT 120A

Recommended Posts

Hello everyone

I connected (by mistake) the 120A current transformers to a 3EM-400 meter.
The current readings are way off; they appear to be scaled up by (at least) a factor of 3 -- could it be the ratio 120/400??
Does anyone know how I can reconstruct the correct data? On the website, both the 120A and 400A CTs are reported to have the same transformer ratio (3000/1)
Can I simply divide by 3?

Thank you
