Easergy P3F30 ANSI 64REF Protection function

[Jaeyoung-Seong]

Hello,
According to the Easergy P3 catalog, the P3F30 model does not support ANSI 64REF (Low impedance). I need to confirm if it supports this function based on high impedance criteria.

Thanks in advance.

Hi,

Normally any overcurrent relay can perform an high impedance protection, then the issue is that there are not always guidance for the CT sizing provided with the User manual.
For Easergy P3, the guidance can be found in a separate application, appended in that post.
