An integrated portable measurement system is described for the study of high speed and high temperature unsteady plasma flows such as those found in the vicinity of high current switching arcs. An array of optical fibers allows the formation of low spatial resolution images, with a maximum capture rate of 1 x 10(6) images per second (1 MHz), with 8 bit intensity resolution. Novel software techn...

Nowaday, the traditional circuit breaker is which action slow, poor reliability, can not meet large grid interconnection and flexible AC transmission requirements. To address those shortcomings of traditional circuit breaker, an idear is put forward that traditional mechanical circuit breaker combinates of power electronic switch-IGCT to build a new type of hybrid circuit breaker device (Hybrid...

Simulating the switching on of an overhead power transmission line (PTL) ultra-high voltage in a dead-end mode, containing significant aperiodic current component, both from switch control key and three-phase automatic reclosing (TARC) cycle, is performed using MATLAB software package. The aim modelling to search find optimal modes electrical operation terms admitting values component assessing...

ENGLISH) Motivated by economic pressures, power utilities are increasingly looking for new ways of reducing their costs while maintaining the quality of supply. A promising concept is predictive or condition based maintenance of high voltage equipment, based on continuos knowledge of each device’s condition. Power transformers and high voltage circuit breakers (HVCBs) have been the focus of att...

Solid-state circuit breakers (SSCB) show great promise to become the key element in protection of low-voltage direct current microgrids. SSCBs operate microsecond range and employ semi-conductor devices that have strict safe operation area limits. Therefore, design SSCB needs consider effects fault detection delays limitations. This paper derives criteria effect different methods with under var...

The purpose of this paper is to acquire the remote electrical parameters like Voltage, Current, and Frequency from Smart grid and send these real time values over GSM network using GSM Modem/phone along with temperature at power station. This project is also designed to protect the electrical circuitry by operating an Electromagnetic Relay. The Relay can be used to operate a Circuit Breaker to ...
