电压互感器

[中文适用范围]： 适用于频率为 15 Hz 至 100 Hz 的电气测量仪器和电气保护装置中使用的新型电压互感器。一般要求适用于所有电压互感器，但对于某些类型，例如电容式电压互感器，这些要求可能会在相应章节中进行修改。尽管这些要求基本上涉及具有独立绕组的变压器，但在适当的情况下，它们也适用于自耦变压器。该标准不适用于实验室使用的变压器。 [外文原描述]： Applies to new voltage transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz. The general requirements apply to all voltage transformers, but, for certain types, e.g. capacitor voltage transformers, the requirements are subject to the modifications stated in the appropriate chapter. Although the requirements relate basically to transformers with separate windings, they are also applicable, where appropriate, to autotransformers. The standard does not apply to transformers for use in laboratories.
