InfoSurge Pro can accommodate many commonly used surge protection devices (SPDs), including open surge tanks, closed surge tanks, and several types of valves.
In a surge analysis, SPDs are placed on a junction. A junction with an SPD should have only one pipe connected to each side. Some attributes used in SPDs can be calculated with the Model Explorer Auxiliary Calculators.
The Resistance Calculator can be especially helpful when resistance values are required. Almost all SPDs have inflow and outflow resistances, representing the resistance into and out of the pipe network, respectively.
To install an SPD:
Note that if a junction node is selected, but the Surge Protection Device button is disabled, a demand change curve has already been defined for it.
To change a node to an SPD
There are several output fields for SPDs, representing things like pipeline pressure, air volume, and flow measured at specific points in the network.
