Abstract In order to clarify the distribution law of ultraviolet photon field in gas insulated switchgear busbar, meanwhile correct detection range sensor, optical model busbar based on uniform theory diffraction is proposed ray tracing. distributions radiation fields are calculated when partial discharge occurs at key positions such as basin insulator and conductor. Based average irradiance, m...

Arc faults in photovoltaic (PV) modules have caused multiple rooftop fires. The arc generates a high-temperature plasma that ignites surrounding materials and subsequently spreads the fire to the building structure. While there are many possible locations in PV systems and PV modules where arcs could initiate, bypass diodes have been suspected of triggering arc faults in some modules. In order ...

3) the superimposed current is detected within a defined time window after fault inception. The relay will not respond to any disturbance outside this window. By this arrangement, the superimposed currents due to switching and energization generated are effectively excluded; 4) the proposed technique cannot detect the operation of the remote circuit breaker (CB) when one of the parallel lines i...

most network charges are based on components’ thermal limits providing correct economic signals to reinforcing network transformers and lines. However, less attention is drawn to the reinforcement cost driven by nodal voltage limits, particularly those resulting from contingencies. In this work, a new charging approach is proposed in which busbar power perturbation is linked to busbar voltage d...

A fresh attempt has been made to develop a new algorithm for optimal power flow (OPF) using Fletcher's quadratic-programming method. The new algorithm considers two decoupled subproblems needing minimum cost of generation and minimum system-transmission losses. These have been solved sequentially to achieve optimal allocation of real and reactive power generation and transformer tap settings wi...

This paper presents a systematic investigation of the impact physical parameters such as dimensions, apertures and terminals, on busbar inductance. A planar laminated with copper conductors polyamide insulator is studied using 3D FEM (Finite Element Modelling) based simulation software. The dimensions conductor length, width thickness, depth insulator, effects aperture number, size, position co...
