摘要：

The operating principle and hardware configuration of the instrument based on AT89C51 for testing breakdown voltage of the dielectric oil is introduced. The method to collect the breakout current through photoelectric isolation is proved when the dielectric oil was broken out. The question about the system work stability in the condition of strive electromagnetism interfere is proposed. At last the realizing solution of high reliability reset circuit based on MAX706 is given. Practice shows that the instrument is stable and reliable.
