The Breakdown module of the Protector allows you to determine which pipes in a hydraulic network will need to be closed during the event of a pipe break.
Identify which pipes contain shut-off valves and which do not. A Breakdown simulation allows you to accurately identify pipes that can and should be closed in order to isolate a pipe element from the rest of the water system.
Use this to identify the contaminant source node. You can specify the display color using the Color on Map section below. Use the Browsebutton to select the source node in the map view.
Include Active Valves - Click on this checkbox to include active valves as closable devices.
Include Active Pumps - Click on this checkbox to include active pumps as closable devices.
All pipes in the domain that are capable of being closed will be be evaluated during the Isolation simulation. You can group these pipes in the form of a domain. Use the Edit Domain button to open the Domain Manager.
Select all pipes in the system that are capable of being closed that will be be evaluated during the Isolation simulation. You can group these pipes in the form of a graphical selection. Use the Selection button to select the pipes in the map view.
