Gas Traces

Isolation Trace

This trace makes use of Esri’s Isolation tracer.

We use the following parameters:

• Retrieve the GasDistributionTierName from the Gas Domain configuration

• Functions are set to an empty list

• Do NOT Validate Consistency

• Include barriers with results

• Include isolated features

• Barriers are set to Regulator and Isolating devices

• Filter results to show only meters, pipes, and open valves

We include barriers in trace results in order to include open valves. If set to false, open valves are not returned. We filter our trace results to show meters, pipes, and open valves in order to illuminate which valves should be closed to isolate a portion of the gas network.

System Trace

This trace uses Esri’s Connected Trace.

We use the following parameters:

• Retrieve the GasDistributionTierName from the Gas Domain configuration

• Functions are set to an empty list

• Target tier and Source tier are null

• Do NOT Validate Consistency

• Sets the barriers if there are squeeze offs

• Include barriers with results
