I was happy to soon... This tables are working excellent for 3ph and 1ph fault, but for 2ph is not matching to the real injected current.

HI.... I finally found this factors in the manual... Thank you for pointing me... Now it's clear. Can't believe I didn't see that. Thanks one more time.

Thanks a lot. This is very helpful. Just one more thing. How come I get 226mA for 2Ph injection and 200mA for 3ph injection for HV side. According to attached table, correction factor should be 1, but I have 226/200=1.13? This is confusing me....

Transformer differential protection (87) Siemens 7UTx relay

Hi again, I hope somebody can help me with my problem which I describe earlier... I will try to write it more detail and with easier example.... So i have differential protection relay and I would like to test pick up of differential protection, for example, for Yy0 transformer vector group. If...

Hello, I have one differential relay and I'am trying to test transformer differential protection. Using current injection test set I inject currents only from side of transformer. For example, pick up value for differential protection is 500mA (secondary value): - I inject in all three phases...
