IEC 62475:2010适用于高压和低压设备的大电流测试和测量。它涉及稳态和短时直流电（如在大功率直流测试中遇到的）、稳态和短时交流电（如在大功率交流测试中遇到的）以及脉冲电流。一般来说，本国际标准中考虑了100 A以上的电流，尽管在试验中可能会出现小于100 A的电流。本标准还包括雷电冲击试验期间的故障检测。

IEC 62475:2010 is applicable to high-current testing and measurements on both high-voltage and low-voltage equipment. It deals with steady-state and short-time direct current (as e.g. encountered in high-power d.c. testing), steady-state and short-time alternating current (as e.g. encountered in high-power a.c. testing), and impulse-current. In general, currents above 100 A are considered in this International Standard, although currents less than this can occur in tests. This standard also covers fault detection during, for example, lightning impulse testing.
