NettetRecommended voltages are: output line-to-line voltage of generator V L − L g = 677 V, input DC voltage of inverter V bat = V DC = 600 V, output line-to-line voltage of inverter V L − L i = 240 V, power system voltage V L − L s =. 480 V, the 2 transformers are of the Δ-Y type connected to the generator and of the Y-Δ type connected to the power system. The line-to-line voltage set has a magnitude that is larger than the line-ground voltage by a factor of 3. Line-to-line voltages are phase shifted by 30 o ahead of line-to-neutral voltages. Clearly, line-to-line voltages themselves form a three-phase set just as do line-to-neutral voltages.

When determining AC voltage you will want to consider both line-to-line and line-to-ground voltage. For Power Line Filters the voltage will normally be one of the following: 120/208 VAC 277/480 VAC 24-1000 VDC Current and Number of Paths/Phases

Nettet9. aug. 2024 · The conductors between a voltage source and a load are called lines, and the voltage between any two lines is called line voltage. The voltage measured between any line and neutral is called phase voltage. For example, for a 208Y/120 volt service, the line voltage is 208 Volts, and the phase voltage is 120 Volts.
