PD data alarm
Description
Primary Phase B – PDI Polar Plot
Trend Status
The PDI change for Primary B in the polar plot is
above a given threshold (see Period to calculate
PD trend, PDI trend warning and PDI trend alarm
in Table 4)
Primary Phase C – PDI Polar Plot
Trend Status
The PDI change for Primary C in the polar plot is
above a given threshold (see Period to calculate
PD trend, PDI trend warning and PDI trend alarm
in Table 4)
Bushing data alarms
The following warnings/alarms may be triggered by bushing monitoring events.
Bushing data alarm
