标准范围

IEC 60034-27-3:20 15提供了旋转电机定子绕组绝缘介电耗散系数测量的测试程序和测试结果解释指南。这些指南适用于额定电压为6 kV及以上的带导电槽涂层的旋转电机。本标准适用于铁芯外部的单个形状绕组定子线棒和线圈（未安装）、安装在铁芯中的单个定子线棒和线圈以及处于新的或老化状态的机器的完整形状绕组定子绕组。与先前出版物IEC TR 60894:1987相比，本版本包括以下重大技术变更:-包括耗散因子和电容的数字测量；-包括耗散因子值的限制；-测量技术的详细描述；范围扩展到完整的绕组。

IEC 60034-27-3:2015 provides guidelines for the test procedures and the interpretation of test results for dielectric dissipation factor measurements on the stator winding insulation of rotating electrical machines. These guidelines are valid for rotating electrical machines with conductive slot coatings operating at a rated voltage of 6 kV and higher. This standard applies to individual form-wound stator bars and coils outside a core (uninstalled), individual stator bars and coils installed in a core and complete form-wound stator winding of machines in new or aged condition. This edition includes the following significant technical changes with respect to the previous publication IEC TR 60894:1987:
- inclusion of digital measurement of dissipation factor and capacitance;
- inclusion of limits for dissipation factor values;
- detailed description of measuring techniques; extension of scope to complete windings.
