Question

In 3-phase a.c system the magnitude of the voltage between two phases are-a) 230 V b)415 V c)150V d) 300V.​

Answer 1

it was the basic question of electrical engineering  the  magnitude of voltage between two phases are aproximatley equals to 415v hence option (b) is correct.

Answer 2

In 3-phase a.c system the magnitude of the voltage between two phases are - a) 230 V

Explanation:

• A wye system allows the use of two different voltages from all three phases, such as a 230/400 V system.
• Which provides 230 V between the neutral and any one of the phases, and 400 V across any two phases.
• The voltage between two line is called line voltage.
• 3 phase system is expressed with line voltages.
• The line voltage is 440 volt. Also the voltage between any one phase and neutral for a 3 phase system is 230 volts.
