Development of an Overall Condition Monitoring System of High Voltage SF6 Circuit Breaker
With the rapid development of arts of sensors and IT, on-line monitoring of circuit breaker is now desirable and practical for electric power utilities. This paper describes a set of overall on-line monitoring systems that was developed to control and monitor the condition of SF6 circuit breaker with different type of sensors and microcomputer based controller. The aim of the developed system i...
متن کاملSF6 High Voltage Circuit Breaker Contact Systems Under Lightning Impulse and Very Fast Transient Voltage Stress
In the past few years gas insulated high voltage circuit breakers have improved considerably, in particular with respect to required drive energy for operation, compactness and reliability. A further reduction in size implies increasing operational field stress inside the breaker and, thus, a reduction in built-in safety margins. If the design comes closer to its physical limits, in particular ...
متن کاملAnalysis of Electric Field and Polarization of SF6 Circuit Breaker to Approach a Suitable Structure
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...
متن کاملAn Innovative Simple Test Circuit for Single-Phase Short Circuit Making Test of High-Voltage Switching Devices
Nowadays, high-voltage circuit breakers have reached such high short-circuit capabilities that testing them under the full rated voltage is generally not possible with direct tests, and they are conducted by using the synthetic test methods. Although the phenomena associated with making tests is of particular importance especially in case of load break switches, but making tests are rather d...
متن کاملDevelopment of non-intrusive monitoring for reactive switching of high voltage circuit breaker
High-voltage circuit breakers are among the most important equipments for ensuring the efficient and safe operation of an electric power system. On occasion, circuit breaker operators may wish to check whether equipment is performing satisfactorily and whether controlled switching systems are producing reliable and repeatable stress control. Monitoring of voltage and current waveforms during sw...
