The ionic space charge in the micro-voids of water tree will produce a period vibration by AC voltage stimulating. Under superposition voltage, the vibration can impel the ion penetrating into the tiny crackle between micro-voids of water tree and lead to a change in the conductivity of water tree. With this the ultra-low frequency spatial current signal of the water tree would be emerged in detecting circuit. The polarization and depolarization of the polar end-group of the PE formed in water tree developing will also contribute to this special signal.

This thesis deals with oil-water flow rate measurement using a venturi and develops a differential pressure-based two-phase flow rate measurement model, which does a terrific job with the use of a water fraction device. Meanwhile, Coriolis flow rate meter is also studied in the oil-water two-phase flow measurement and a SVM-based single-phase flow rate prediction method is proposed, realizing the prediction of single-phase flow rates. To overcome the disadvantages of both venturi and Coriolis flow meters, a double parameter measurement method is put forward, which combines the two meters and solves the problem of oil-water flow rate measurement. Last but not least, on the basis of the study of two-phase flow, a device for the separation of gas and liquid is designed and realizes the flow rate measurement of three-phase flow as oil, gas and water.
