Answer / Vibha Yadav

In electrical engineering, the term `VTG` stands for Voltage-To-Ground. In a three-phase star connection, the line-to-ground voltage (V_LG) is related to the line-to-neutral voltage (V_LN) by the square root of 3 (sqrt(3)). This is due to the symmetrical arrangement of the voltages in a star connection. The mathematical relationship is V_LG = sqrt(3) * V_LN.
