SUPPLY INTERRUPTION

A district heating network may have supply interruptions from time to time. Use the Supply interruption form to calculate and view the scopes of the supply interruptions and their network objects. You can use the Supply interruption form to determine the customers affected if a conduit gets broken as well as the extent of the scope of the supply interruption. The Supply interruption  form is also a useful tool for maintenance and modification work. The form also provides information on which valves need to be closed during the supply interruption.

Creating supply interruptions

To create a new supply interruption, use the Object selection button to select a conduit or valve on the Supply interruption form. Crop a valve or conduit in the desired area on the map. After the selection, the program automatically performs the calculation, and the supply interruption area and its consumer points and valves to be closed (S) are highlighted on the map.

Note! When the Supply interruption layer is active, you can see supply interruptions created earlier. In such a case, use the Select supply interruption option.
