摘　　要：介绍一种在电力系统中实用、新颖。快速测量感性负载（如变压器）直流电阻的高准确度智能化仪器的研制。整个测试过程由ＭＣＳ－５１系列单片机自动实现自检、过渡过程分析、数据采集分析和过热保护，并给出了产品的性能指标。The research-method and actual test-effect of a novel fast high-precision and intel- ligent test-set for the DCR (direction current resistance) of the perceptual load in the elec- tric power system(for example transformer)is introduced in this paper. This instrument can be controlled by the system of the singe-chip microprocessor, and it can test automaticly by it- self, and can analyze the process of the test, and can collect data and safeguard superhot. This paper will provide with some key targets of the properties of the instrument. Some im- portant segment is expatiated on, and the performance is given, it holds the advantage of high-precision, low-noise, low power consumption, better anti-interference,simple and safe operation and so on.
