摘要
论述了变压器局部放电源的电－声和声－声定位原理及算法，利用研制的高灵敏度超声传感器和编制的定位软件在模拟油箱中进行了试验，结果表明声－声定位法比电－声定位法的偏差要大。
The principle and algorithm of locating PD sources in transformer is discussed. Using the developed high sensitivity supersonic transducer and locating software, experiments have been made in simulative oil tank. Results show that the error of Supersonicsupersonic locating method is greater than that in Electricsupersonic method.
