Disturbance Direction Indicators in TGML

Overview

DDD Indicators in TGML indicates the disturbance direction associated to an electrical one-line diagram. The indicators are associated with the power quality meters that records the direction of the disturbance. The indicators show the type of PQ disturbance (sag / swell / transient) and the disturbance direction relative to the metering point. By combining the information from multiple devices in a network we can then identify from where the disturbance originated. Up to 5 latest PQ disturbance incidents are displayed.

The TGML DDD latest PQ Incidents component filters incidents based on the access of the user group assigned to the source. A user has access only to the sources included in the group that they are a member of.

This is an example of showing disturbance direction on a single line diagram.
