A large number of ground coils are used in superconducting magnetic levitation (Maglev) systems; therefore, it has been considered that condition monitoring systems for the ground coils are mounted on Maglev trains. We have been studying radio sensin

We have been studying radio sensing techniques to detect partial discharges (PDs) occurring in propulsion coils used in superconducting magnetic levitation (Maglev) systems. In this study, preliminary experiments were carried out for setting an objec

Condition monitoring techniques for ground coils used in superconducting magnetic levitation (Maglev) systems are required. In this study, an on-board radio interferometer system with a vector-antenna was developed to locate partial discharge (PD) so

In order to evaluate the insulation condition of gas insulated switchgear (GIS) by using the ultra-high frequency (UHF) method, attempt to estimate PD current using the finite difference time domain (FDTD) method was carried out. The influence of PD

Superconducting magnetic levitation (Maglev) systems require a large number of ground coils: propulsion coils and levitation-guidance coils, therefore how to monitor the condition of ground coils is a big issue for the real operation. In our previous

The detection sensitivity of an on-board radio interferometer system for indicating abnormal propulsion coils in superconducting magnetic levitation (Maglev) systems was improved by shortening the antenna spacing from 1.0m to 0.5m and introducing the

A new method for locating the position of partial discharge (PD), which occurs on distribution line, is presented. The method uses the direction-of-arrival (DOA) of electromagnetic (EM) waves emitted from PD source. The DOAs of EM waves in azimuth an

Plasma Science and Technology. 13:708-713
In this paper, a one-dimensional discharge model is employed to study multi-pulse phenomena in Ar dielectric barrier discharge (DBD) under atmospheric pressure. The finite-element method is employed to solve the model. The influences of applied volta
