Question

A balanced three-phase Y load has one phase voltage of Vcn=239.4∠26⋅V. If the phase sequence is negative sequence i.e. acb, calculate the magnitude of the line-to-line voltage Vca in Volt.

Answer 1

The magnitude of the line-to-line voltage Vca in a three-phase Y load with negative sequence can be calculated by multiplying the phase voltage by √3.

Step-by-step explanation:

To calculate the magnitude of the line-to-line voltage Vca in a three-phase Y load with negative sequence, we can use the relationship between the phase voltages in a Y load. In a Y load, the line-to-line voltage (VLL) is equal to √3 times the phase voltage (Vph). Given that one phase voltage is Vcn = 239.4∠26° V, we can calculate VLL as follows:

VLL = √3 * Vph = √3 * 239.4∠26° V

Using a calculator, we can find that VLL is approximately 414.65∠26° V.
