Single-Phase Modeling

EasyPower supports modeling single-phase equipment and protective devices in the one-line. EasyPower performs short circuit and arc flash calculations and displays coordination TCCs for single-phase equipment and devices.

Some of the options available include:

• Single-phase tap from three-phase equipment using a line-to-line or line-to-neutral connection.
• Single-phase tap from single-phase three-wire equipment using a line-to-line or line-to-neutral connection (for example, 120/240V).
• Single-phase short circuit calculations including reports and equipment duty analysis.
• Single-phase arc-flash calculations including reports and labels.
• Single-phase protective device coordination and TCC plots.
• Single-phase design load calculations.

Note: Single-phase equipment is not currently supported in harmonics, auto coordination, auto design, dynamic stability, or transient motor starting analysis. Single-phase equipment is supported in power flow only if your license includes the unbalanced power flow feature.

Note: Single-phase modifications are restricted in scenarios. See Scenario Restrictions for Single Phase for more information.
