Firstly, we research the Vlasov antenna with reflector mainly. A new method to calculate the radiation of the antenna is founded with Vectorial Theory of Diffraction, and the corresponding program is made. The reflective characters of Vlasov antenna are studied with Moment Methods, and the results show that the total reflected energy is less than 0.25%. The radiation patterns of the antenna are analyzed, and the formulas to estimate the wave beam parameters and to design the antenna are provided. The feasibility of radiating high-order modes by Vlasov antenna is also discussed and verified. The hermetization of the Vlasov antenna is researched and the results show that with such kinds of hermetization the antenna can work under gigawatt level. The design of the mode converter from TEM to TMoi is studied, which is useful when the TEM coaxial mode is radiated by Vlasov antenna. At last, the flared-end Vlasov antenna is also discussed.

If the fault is out of the line, the calculation value of fault component integrated impedance reflects the line capacitive impedance with a greater amplitude; if the fault is on the line, it reflects the system impedance and line impedance with a relatively smaller amplitude. According to the amplitude of the fault component integrated impedance, the fault location can be distinguished.

在外部故障时，该比值反映输电线路上的容抗，其模值较大，内部故障时，该比值反映系统电源阻抗和线路阻抗，其模值相对较小，据此可以区分线路上的内部和外部故障。
