摘　　要：本文介绍了绝缘表面电位试验相比于直流、交流耐压试验在检测发电机定子绕组端部绝缘方面的优势,并对试验原理、试验接线及注意事项进行了阐述。通过案例验证了手包绝缘表面电位试验能够有效检测发电机大修时定子绕组端部手包绝缘处理后的绝缘质量,为电厂电气设备运行维护提供可靠的试验依据。This paper presents the advantage of surface potential test on hand-making insulation for stator windings ends insulation detection, compared with DC or AC withstand voltage test, also details the test principle, connection method and test notes. And through the case, surface potential test on hand-making insulation proved effective for insulation quality detection after stator windings ends maintenance, and the experimental data is useful and reliable for the electrical equipment operation and maintenance in the power plant.
