By detecting the amplitude-frequency response characteristics of various windings of transformer, and comparing the detection results longitudinally or laterally, the possible deformation of transformer windings can be judged according to the variation degree of amplitude-frequency response characteristics ■ Characteristics of transformer windings are measured with frequency sweep method. ■ Quick measuring, measuring of a single winding is within 3 minutes. ■ Digital frequency synthesis, with higher frequency stability. ■ 5000V voltage isolation fully protects safety of the testing computer. ■ Able to load 9 curves at the same time and automatically calculate parameters of each curve and diagnose winding deformations to provide the reference diagnosis conclusion. ■ Software management is humanized with high degree of intelligence. It is compatible to Win7 and Win 10 system. Output impedance Input impedance 1MQ (the response channel is built with 500 matching resistance) Frequency accuracy Frequency sweep manner linear or logarithmic, frequency sweep interval and number of sweep points are freely settable Curve display Mag-freq. curve
