What is it?

The Rules & Events page is where you define Rules and Event-triggers based on data from your monitored power lines. It is currently possible to define rules for temperature, current, sag, clearance, ice load, and ampacity. This page lets you create, edit, and delete rules and event triggers for whole lines and/or specified spans. You can view the defined rules and triggers on this page, together with the triggered events and alarms.

As mentioned previously, you can define rules and triggers for whole lines or specified spans (the line section between two pylons). Events can be of the six following types:

  • Thermal - The temperature of the line is monitored and triggered upon.

  • Current - The current flowing in the conductor is monitored and triggered upon.

  • Clearance - The clearance (lowest distance between conductor and ground) is monitored and triggered upon.

  • Sag - The sag (the vertical difference in level between points of support and the lowest point of the conductor) is monitored and triggered upon.

  • Icing - The amount of ice load [kg/m] is monitored and triggered upon.

  • Ampacity - Where the aggregated ampacity of a line is monitored and triggered upon.

Event Log - The event log contains the triggered events and alarms. Each alarm has a timestamp, color-coding, threshold value, trigger value, duration, and a custom specified comment.

Rules and Event-triggers overview - This overview contains all the specified rules and event-triggers. They are grouped by type (Thermal, Current, Clearance, Sag, Ice Load, and Ampacity), and clicking one of the types expands the type and shows all the defined rules and triggers. It is in this view that the user can create, edit, and delete rules and triggers.

How to use

You, as a user, can use rules and Events for multiple purposes;

Last updated 30/10/2020

  1. Define rules and event triggers to get notifications in-app and/or via SMS or email when a power line goes above or below a defined threshold. This will help you, as a user, to quickly take action on severe alarms in the power grid or inform you of events in the grid.

  2. You can define rules, and event triggers to get statistics of, e.g., how many times your power line equipment has been loaded over/under a specified threshold? How many times has the power line been operated over/under a specified temperature? How many times has the power line had an excessive sag?
