What is the multiplier used in the calculation of voltages on a two-phase system?

In a two-phase system, the multiplier used in voltage calculations is based on the relationship between phase voltage and line voltage. For a two-phase system, the line voltage can be determined by multiplying the phase voltage by the square root of 2, which is approximately 1.41.

This is derived from the geometry of the voltage waveforms in the system, where the phase voltages are 90 degrees apart. Therefore, when calculating the effective line voltage from the phase voltage, you take the phase voltage and multiply it by √2 (approximately 1.41). This squared relationship arises because the line voltage is the vector sum of the two phase voltages.

Thus, in this context, 1.41 serves as the correct multiplier for calculating voltages in a two-phase system, accurately reflecting the relationship of the voltages involved.
