In this premise, the method of no-load current value selection based on charged effective coefficient was raised. The calculation formula of the relationship between charged effective coefficient and no-load current value was deduced from the discrete data. The index of the power factor and harmonic current rate from the actual example showed that using this method, the objective evaluation of the traction's load power quality can be received
