Setting the Nominal System Voltage

Line-to-neutral voltage of three-phase distribution systems is equal to the base kV divided by √3. This table in Options on the System tab can be used to adjust the single-phase tap voltage to a nominal value. If the base kV of the three-phase equipment is not identified in this table, the line-to-neutral tap voltage of single-phase equipment defaults to the base kV divided by √3. An additional setting is provided to allow for a voltage mismatch tolerance when connecting single-phase equipment to three-phase systems.

Note: If you enter a line-to-line voltage on the one-line that is not specified in the table, EasyPower calculates the line-to-neutral voltage using the √3 difference. Similarly, if you enter a line-to-neutral voltage on the one-line that is not specified in the table, EasyPower calculates the line-to-line voltage using the √3 difference.
