    line to phase voltage conversion calculator

    This convenient Line to Phase Voltage Calculator computes phase voltage based on line voltage in three phase three phase systems (Star (Wye) and Delta). Line to Phase Voltage Calculator calculated line-to-line voltage of a three phase system into phase voltage with the right relationship where the connection type is star or delta. In star connections the line voltage is divided by the square root of three to obtain the phase voltage but in delta connection the phase voltage and the line voltage are equal. The calculator is very important to the electricians and engineers, engaged in three phase systems that require proper analysis of the voltage and design of the systems.

    Frequently Asked Questions - Line To Phase Voltage Conversion FAQs:

    How do you calculate phase voltage from line voltage in a three-phase system?

    Each phase voltage (V_phase) in a balanced three-phase system measures V_line divided by the value of √3. A star (Y) connected system uses √3 as the conversion factor to obtain phase voltage from line voltage.

    What is line-to-phase voltage in an electrical system?

    In a three-phase star connection, the voltage that exists between any one line conductor and the neutral point is known as the line-to-phase voltage. Principal voltage measures the difference between the single-phase winding and amounts to less than the voltage between the line conductors.

    How do you calculate the phase voltage from the line voltage in a delta connection?

    When measuring between two line conductors, you obtain line voltage, whereas phase voltage is the measurement between one phase and the neutral point. System voltage in star connections becomes √3 times higher than phase voltage, while both measures stay equal in delta connections.

    How is the phase of voltage determined in a three-phase system?

    The phase of voltage refers to the angular displacement between voltages in different phases. A balanced three-phase system divides its phases through a 120-degree interval. The phase difference calculation requires either phasor diagrams or oscilloscope waveform analysis.

    What is the difference between line voltage and phase voltage?

    Two-line conductors measure the dimension of line voltage, whereas phase voltage indicates the voltage that exists between a single-phase winding and the neutral point. The relation between line and phase voltage stands at √3 times in cases of star connections, but becomes identical in delta connections.
