3、方法:在“不带电” 的回路中,使用频率高于工频的电流注入的理想vs1短路器试验

理论上的限制:不考虑回路中可能存在的非性线; 不直接给出工频阻抗。在注入频率高于工频而远低于TRV频率的条件下,也只能给出单频和多频回路的TRV从零到第一个最大值部分的正确波形和数值。不能正确估算幅值系数。

4、方法:模型网络试验 (瞬态网络分析仪)

理论上的限制:有关网络的非线性和与频率有关的特性的精确资料并非经常能得到。需要对回路元件及其杂散参数有确切的了解。

5、方法:根据回路参数计算

理论上的限制:有关网络的非线性和与频率有关的特性的精确资料并非经常能得到。需要对回路元件及其杂散参数有确切的了解。

6、方法:空载时接通试验变压器

理论上的限制:除非在或接近于电压波峰值处使变压器带电,否则需要对工频电压波前进行校正。
