In order to accurately analyze the dynamic characteristics of the vacuum circuit breaker, a dual-core master-slave processor structure for online monitoring system based on DSP and ARM is proposed. This structure consists of host computer, lower computer and signal processing modules. The lower computer uses DSP as the core, which completes acquisition and data preprocessing of circuit breaker’...

This paper gives a case of large Sub-Station Clean Development Mechanism (CDM) Project to analyze CDM project’s influence on India’s Sustainable Development. SF6 gas is being extensively used in circuit breakers. SF6 gas has the highest Global warming potential which is 23900 times of Carbon Dioxide. Extensive Survey of SubStation using SF6 circuit breaker has been done in a sample state of Ind...

Ultra Wide Band Radio (UWB) is also known as the impulse radio (IR). It will become one of the most competitive technologies, especially in the high speed data transmission, high precision positioning, tracking and other fields; it has broad application prospects in the future. The main function of the highvoltage circuit breaker in the power grid is breaking, closing and carrying run normal cu...

The fault current development in a circuit breaker during a pole-to-ground fault is analyzed for a generic multiterminal HVDC system based on Voltage Source Converters. The paper aims to contribute to the current discussion of which requirements on breaking time and peak current HVDC circuit breakers need to fulfill in such networks either based on OHLs or cables. Therefore, the fault current i...

The automated circuit breaker diagnostic system described in this paper is an extension of the widely used portable circuit breaker testing device concept. The testing devices can be connected to the circuit breaker’s control circuit to record analog and digital signals. The automated system consists of a signal processing module and an expert system module. The two modules process the voltage ...

The electrical substation components are often subject to degradation due to over-voltage or over-current, caused by a short circuit or a lightning. A particular interest is given to the circuit breaker, regarding the importance of its function and its dangerous failure. This component degrades gradually due to the use, and it is also subject to the shock process resulted from the stress of iso...

A circuit breaker is widely used to protect electric power system from fault currents or system errors; in particular, the opening mechanism in a circuit breaker is important to protect current overflow in the electric system. In this paper, multibody dynamic model of a circuit breaker including switch mechanism was developed including the electromagnetic actuator system. Since the opening mech...
