High-speed rail has become popular in China

but the power supply mode of the high-speed rail traction station is special

and its measurement and wiring error analysis and comparison of the three-phase load balancing system are obviously different. In order to grasp the difference

according to the characteristics of one phase of the high-speed railway traction station operating as a public phase and commutation of the transmission line

a phasor diagram analysis of the incorrect wiring of the metering circuit in a real case of a traction station of the Changgan high-speed railway is carried out

and the Ub

Uc reverse connection results in a huge difference between the power supply and the metered power on both sides. After correction

a total of 756

756 yuan of electricity loss during the wrong wiring period is compensated

which provides reference and reference for the electric power industry metering profession in the recovery of electricity at high-speed rail traction stations

which has universal significance.
