HDPM6000 CT Ratio setting

[stephanc_usserv]

Looking for the CT ratio settings for all of the METSEHDPM CTs. I'm currently commissioning a meter and the only CT file that is loaded is the 75:1.834. I need the setting for the 20, 150, 300, 400 and the 800 amp CTs

Sure @Charles_Murison 

Hello @stephanc_usserv 

Can you share the list of CT reference numbers? I will check and share the CT factor and PHCAL values. 

Also confirm the HDPM6000 meter firmware version details. 

Regards,

Can we use 3rd party CTs with the HDPM like Rogowski Coils or any other rope CT?

Hi @sesa353590 

The HDPM6000 CT input terminals will accept only the CTs which has 250mV secondary. 

What the secondary output voltage of Rogowski Coils and rope CT?
