Description
The PF% polar plot amplitude is above a given
threshold on an area defined by Secondary A (see
PF% Polar plot level warning and PF% Polar plot
level alarm in Table 5)
The PF% polar plot amplitude is above a given
threshold on an area defined by Secondary B (see
PF% Polar plot level warning and PF% Polar plot
level alarm in Table 5)
The PF% polar plot amplitude is above a given
threshold on an area defined by Secondary C (see
PF% Polar plot level warning and PF% Polar plot
level alarm in Table 5)
The measured inter-phase angle between Primary
A and B is beyond a given threshold respect the
expected angle (see Phase angle warning and
Phase angle alarm in Table 5)
The measured inter-phase angle between Primary
A and C is beyond a given threshold respect the
expected angle (see Phase angle warning and
Phase angle alarm in Table 5)
The measured inter-phase angle between
Secondary A and B is beyond a given threshold
respect the expected angle (see Phase angle
warning and Phase angle alarm in Table 5)
The measured inter-phase angle between
Secondary A and C is beyond a given threshold
respect the expected angle (see Phase angle
warning and Phase angle alarm in Table 5)
