UHV-311 based on the measurement of the windings characteristic parameters inside the transformer, the tester using the world's developed countries sound internal fault frequency response analysis (FRA) method, able to make an accurate internal transformer fault judgment. After the completion of the design and manufacture transformers, coils and its internal structure to be finalized, therefore a transformer coil winding, if the voltage level, method of winding are the same, each coil corresponding parameters (Ci, Li) is determined. Thus the frequency domain response characteristics of each coil...

5. When measuring the transformer, the wiring personnel can arbitrarily lay the signal input and output leads without affecting the measurement results. The wiring personnel can stay on the transformer oil tank without coming down, reducing labor intensity. 6. The amplitude-frequency characteristics meet the national technical indicators for amplitude-frequency characteristic testers. The horizontal axis (frequency) has two types of linear and logarithmic divisions, so the printed curve can be a linear or logarithmic division curve, and the user can choose according to actual needs. 7. The instrument...
