东南大学研制成功电力变压器局部放电超声定位仪。该仪器由微机和传感器等部分组成，属超高压变压器机电一体化产品。在微机控制下，能自动测出绝缘局部放电故障，并可加以定位，能对５００ＰＣ（微微库仑）放电量的局部放电故障（２００ｍｍ的空间球）进行定位。监测精度高，? Southeast University successfully developed partial discharge power transformers ultrasonic locator. The instrument by the microcomputer and sensors and other components, is a mere high voltage transformer mechatronics products. Under the computer control, it can automatically detect the insulation partial discharge fault and can be positioned to locate the partial discharge fault (200mm space ball) of 500PC (slight coulomb) discharge capacity. High monitoring accuracy,?
