InfoSurge Pro can accommodate many commonly used surge protection devices (SPDs),
00:11
including open surge tanks, closed surge tanks, and several types of valves.
00:18
If you know what a specific device does, you can generally find a specific model SPD to match that behavior.
00:27
In a surge analysis, SPDs are placed on a junction.
00:32
A junction with an SPD should have only one pipe connected to each side.
00:39
Some attributes used in SPDs can be calculated with the Auxiliary Calculators button of the Attribute Browser.
00:47
The Resistance Calculator can be especially helpful when resistance values are required.
00:54
Almost all SPDs have inflow and outflow resistances,
00:60
representing the resistance into and out of the pipe network, respectively.
01:06
Installing an SPD is as simple as selecting a junction and clicking Surge Protection Device.
01:15
A dialog appears allowing you to select the type of SPD you want to create.
01:21
Note that if you have a junction node selected but the Surge Protection Device button is disabled,
01:28
a demand change curve has already been defined for it.
01:32
To change a node to an SPD, click the Demand Change button,
01:38
and then in the Junction Demand Change dialog, click Purge.
01:44
There are several output fields for SPDs,
01:47
representing things like pipeline pressure, air volume, and flow measured at specific points in the network.
01:57
Inlet Pressure is the pipe line pressure at a node with an SPD assigned to it.
02:04
Outlet Pressure is the pressure measured at an SPD.
02:09
Side 1 Flow is flow measured from upstream.
02:14
Side 2 Flow is flow to downstream.
02:19
External Flow is flow to an SPD.
02:23
External Volume is the air volume of an SPD.
