With the increasing installations of solar energy, electric vehicles, and other dc-nature power devices in modern systems, short-circuit protection high-power dc circuits is critical HVDC transmission MVDC distribution networks. As a promising protective device, Z-source Circuit Breaker (ZCB) has some unique good features over approaches. But, under circumstance slow-developing faults, ZCB migh...

SF6, which is currently widely used in gas-insulated power transmission equipment, a greenhouse gas with very strong effect. Therefore, developing environmentally friendly insulation equipment to gradually reduce the use of SF6 has become hot research topic. As most potential alternative gas, C4F7N great significance study electrical characteristics medium-voltage switching field promote green ...

This paper presents the design, construction and testing of a new capacitive tactile sensor for measurement of normal tactile force. The operation of proposed sensor has been investigated in ASTABLE and MONOSTABLE circuits. According to the results of these circuits the deviation of ASTABLE circuit results is less than MONOSTABLE circuit results. In addition, the results obtained from ASTABLE c...

A new DC fault current limiter (FCL)-based circuit breaker (CB) for microgrid (MG) clusters is proposed in this paper. The analytical expressions of the a bidirectional interlink DC/DC converter interconnection line two nearby MGs are analyzed detail. Meanwhile, clearing solution (based on using FCL series with breaker) proposed. This structure offers low complexity, cost, and power losses. To ...
