标准摘要
[中文适用范围]： iec 60156:2025 标准及其红条版本（rlv）包含了官方的国际电工委员会（iec）标准及其修订版。该修订版仅提供英文版本，为快速简便地比较官方iec标准与其前一版本的所有更改提供了途径。iec 60156:2025 规定了在工频下测定绝缘液体介电击穿电压的方法。试验程序在一个指定的设备中进行,其中油样被施加逐渐增强的交流电场,直至发生击穿。该方法适用于粘度不超过350 mm²/s（40℃）的所有类型的绝缘液体。它既适用于在交付时对未使用的液体进行验收测试，也适用于在设备监控和维护期间确定取样的状态。 [外文原描述]： IEC 60156:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60156:2025 specifies the method for determining the dielectric breakdown voltage of insulating liquids at power frequency. The test procedure is performed in a specified apparatus, where the oil sample is subjected to an increasing AC electrical field until breakdown occurs. The method applies to all types of insulating liquids of nominal viscosity up to 350 mm2/s at 40 °C. It is appropriate both for acceptance testing on unused liquids at the time of their delivery and for establishing the condition of samples taken in monitoring and maintenance of equipment.
