Issue:
A sag event has occurred on an ION or PowerLogic meter, but the duration does not display through a data log viewer.
Product Line:
ION Enterprise 6.0 SP1 / SPM 7.0.1 / PME 7.x / PME 8.x
Environment:
Vista
Cause:
All meter power quality events (sag, swells, transients) have two separate 'Disturbance Start' and 'Disturbance End' timestamps. PME uses the difference between these two to calculate the duration. During a sag event if a meter's control power is wired in parallel to the voltage inputs this can cause the meter to only register the 'Disturbance Start' event.
Resolution:
If a duration time stamp is needed the meter should be wired with separate control power from the voltage inputs such as a battery back up. This will ensure that if the voltage inputs should go to zero the meter will still remain powered to capture both the start and end events.
