Figure 85: Stable phase C-to-earth fault current flowing through the measuring
point of FPIPTOC in a compensated network
In Figure 85, the fault occurs at time 0.2 sec. On the right-hand side, the result of
faulted phase selection (Equations 20 - 22) and fault passage indication (phase angles
of
Equations 23 - 25 and ΔI
EF
/ΔI
o
ratio of Equation 26) are shown.
