摘要
介绍了金属护套在不同的交叉互联接地方式下,电缆线路参数的理论计算和实测方法;结合现场试验经验,分析了电缆线路参数——相序电流的通路变化对相序阻抗的影响,探讨电缆线路参数的变化规律特点,保证电缆线路参数的正确测量。
The calculation and measurement of the power cable line parameters at different cross connections for grounding of the metallic sheath are presented. The effect of the variation in phase sequence current loop on the phase sequence impedance was analyzed and the characteristics of the variation in cable line parameters was investigated in combination of field testing experiences, in a view to ensure proper measurement of the cable line parameters.
