Disturbance Direction

Disturbance Direction identifies the origin of a voltage disturbance (sag/swell/transient).

Disturbance direction calculations are done by the monitoring devices. A device determines the direction of the origin of a disturbance as either Upstream or Downstream from the device location. It is possible to identify the likely origin of a disturbance within a power system by combining the direction information from multiple devices in the network. For alarms, the disturbance direction shown in the software is the direction determined by the device that is associated with the alarm. For incidents, it is the direction determined by the representative device for the incident.

Use Disturbance Direction to analyze the likely origin of voltage disturbance events in your power system.

Prerequisites

The monitoring devices must be capable of detecting and logging the disturbance direction.
