Hi,

I am working in the adjust of the function Broken Conductor. I used the protection MiCOM P44y, ABB REL 670 and GE D60.
The function of the GE and MiCOM use the ratio I2/I1. The function of the ABB use tha phase currents.

Which is the adjust of time that is recomend for this function?
I need a rank of time for the delay of the pick up.

Thanks you a lot
