Overview of Current Research into Low-Voltage Circuit Breakers
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....
متن کاملReliability Based Optimal Preventive Maintenance Policy for High Voltage Circuit Breakers in Power Plants
Electric power industry have always try to provide reliable electricity to customers and at the same time decrease system costs. High Voltage circuit-breakers are an essential part of the power network. This study has developed a maintenance and replacement scheduling model for high voltage circuit- breakers that minimize maintenance costs while maintaining the acceptable reliability. This mo...
متن کاملInvestigating Characteristics of N2, CO2 and CF3I in Contrast to High Current Arcs in Circuit Breakers to Choose a Suitable Substitute for SF6
Specific and sensitive operation of circuit breakers makes an individual position for them in power networks. Circuit breakers are at the central gravity of variations and execution operations. Therefore, an optimum operation is the main reason to investigate about new gases to be used in MV and HV circuit breakers instead of SF6. The arc process has enormous complexity because of hydrodynamic ...
متن کاملTHESIS FOR THE DEGREE OF LICENTIATE OF ENGINEERING Controlled Switching of High Voltage SF6 Circuit Breakers for Fault Interruption
This thesis report describes an adaptive, self-checking algorithm for controlled short-circuit (fault) interruption in conjunction with high voltage alternating current SF6 circuitbreakers. The primary objective of controlled short-circuit interruption is to restrict the arcing time of the circuit-breaker to a nominal window (near the minimum arcing time) and thereby seek to reduce the electric...
متن کاملModel-aided Diagnosis for High Voltage Circuit Breakers
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...
