Study of Testing Methods and Apparatus for Partial Discharge Location in Large Power Transformer

本文概述了80年代国内外局部放电超声定位的发展概况,文中介绍了JFD1系统的技术特点,着重研究介绍了有关定位技术和抗干扰措施,最后给出了JFD1系统的现场实测结果。有关结果表明,本文提出的方法和装置是可行的、有效的。

In this paper, the resent development of partial discharge acoustic location is briefly introduced. The paper presents the characteristics of JFD1 system with the emphasis on acoustic locating technique and anti-interference measures. The on-site testing results of JFD1 system is also given. From the results, it is confirmed that the methodsand apparatus described in this paper are feasible and effective.
