Directly earthed or small impedance network (67N)
Figure. 5.3.5 - 95. Angle tracking of I0dir> function (directly earthed or small impedance network).
In a directly earthed network the amplitude of a single-phase fault current is similar to the amplitude of
a short-circuit current. Directly earthed or small impedance network schemes are normal in
transmission, distribution and industry.
The phase angle setting of the tripping area is adjustable as is the base direction of the area (angle
offset).
