The high amplitude and steep overvoltage generated by the breaking of vacuum circuit breaker in wind farm damages inter-turn insulation transformer. There is a certain difference between simulation results traditional reignition model measured overvoltage. It necessary to improve simulate condition transformer more accurately then select appropriate protection measures. In this paper, based on ...

The low-voltage circuit breaker has been used for many years for network and persons protection. The review papers existing on these devices generally deal with electrical aspects or macroscopic information on the arc but few concern the “fine” understanding of arc behaviour from its ignition between the opening contact to the current limitation stage due to its presence in the splitter plates....

Owing to very rapid growth in electronics and technology, it has become very essential to maintain power quality at the consumer end. Since power quality has vast no of assets, mainly important and frequently occurring disturbances are considered in this paper. Power quality is mainly defined by disturbances associated with voltage. However, the voltage disturbances can be classified based on t...

In medium voltage vacuum circuit breakers, in order to achieve an even distribution of force along the entire length drive shaft, mechanism is made per phase, that is, a separate electromagnet installed under each pole. The analysis designs and features operation breakers with phase electromagnetic carried out. Deficiencies these drives have been identified. design breaker kinematic diagram mon...

Abstract To improve the accuracy of mechanical fault diagnosis operating mechanism and fully exploit characteristic information in vibration signal high-voltage circuit breaker, a method breaker based on deep self-encoding network is proposed. First, switch extracted, wavelet packet conversion performed, each frequency band divided into equal times. The energy time–frequency subplane then calcu...

In this paper a new approach to the analysis of test results for circuit breakers is discussed. It is implemented through new software called Automated Circuit Breaker Monitoring system ACBM. The circuit breaker performance is evaluated based on the analysis of Digital Fault Recorder (DFR) recordings taken from circuit breaker control circuitry. This paper describes the testing procedure and us...
