Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...

The subject of arc fault detection and circuit interruption has gained a lot of attention in recent years, particularly in the aviation industry. This is primarily due to a spate of in-flight fires which have been linked to faulty electrical systems and wiring on aircraft. Typical causes of faults are wiring chafing, dust build up and moisture [1][2]. Until recently, aircraft circuit breakers, ...

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...

HVDC circuit breaker with sufficient interruption capability and interruption speed, as a key technology to enable HVDC transmission in meshed multi terminal networks do not yet exist. AC circuit breakers in combination with a passive resonance path are used to build HVDC breakers even though the requirements for AC breaking strongly differ from requirements for DC current interruption. Current...

This paper presents the flow field analysis in the Puffer-tyep (P-T) circuit breakers. There are many problems in analyzing the flow field in circuit breakers such as shock wave, complex geometry, moving boundary and so on. For the cold gas analysis, the flow field computation for the high voltage gas blast circuit breaker with the moving boundary by meshfree (FGCBM) method[1,2] is employed to ...
