电流检修法在差动保护装置中，电流互感器是关键设备，同时也是构成差动保护模式的重要因素。在对电流互感器进行安装使用过程中，需要对它的具体型号进行合理选择，保证型号、规格的合理无误。一般来说，是采用差动保护专用的D级别电流互感器；同时在经过保护装置外围的稳态短路电流时，在电流值达到大后把差动保护回路的二次负荷控制在10%范围内，不能超出这一范围。负荷检修法在电流互感器的运行中，系统运行负荷过大也会对其产生一定影响，具体就是超荷运行，这样会降低其使用寿命。

This is the General Pure Cable in UL for the UL1581. The experiment required several samples to be laid on a vertical 8 foot high bracket and 20 minutes with the specified 20KW ribbon spray lamp (70,000 BTU/Hr). for flame not to spread to the upper end of the cable and self-extinguishing. UL1581 is similar to iec 60332-3c except that the number of cable roots is different. There is no smoke concentration specification for commercial grade cables, which is generally only used for horizontal running of the same floor, but not for vertical wiring of the floor.
