摘要
介绍了一种实用、新颖、能快速测量变压器直流电阻的高精度仪器的研制思路及现场测试效果 ,对其中某些关键环节进行了详细阐述 ,并给出了性能指标 ,具有高精度、低噪声、小功耗和抗干扰能力强等优点。
The research method and actual test effect of a novel fast high precision test set for the DCR(direction current resistance)of transformer is introduced in this paper. Some important segment is expatiated on, and the performance is gotten, it holds the advantage of high precision, low noise, low power consumption, better anti interference and so on.
