介绍了后备阻抗保护对变压器绕组短路灵敏度很低。
It is described that the sensitivity of impedance back up protection for transformer wind short circuit is very low.
由于电弧电阻非线性、时变性、高阻的特点，使得常规原理馈线保护中的阻抗保护、电流速断保护往往不能正确动作。
For the arc resistance is nonlinear and high, the conventional feeder protections, such as impedance protection and current protection, maybe fail to trip off.
