The interruption behaviours of a high voltage vacuum circuit breaker (VCB) have been investigated in detail [1]–[3]. A VCB has several specific interruption behaviours compared to an SF6 gas circuit breaker (GCB). In particular, a higher thermal interruption capability and a high frequency (HF) re-ignition and HF interruption phenomena might cause switching overvoltage. Interruption behaviours such...
The LSI design methodology against Differential Power Analysis (DPA) is important to realize a tamper-resistant cryptographic circuit. In order to verify the DPA resistance before ASIC fabrication, the DPA verification using FPGA is commonly used. However, power traces of ASIC differ from that of FPGA, so the DPA verification on FPGA cannot guarantee the DPA resistance on ASIC. On the other hand,...
The development of EHV and UHV substation equipment have been proceeding to cope with the electricity demand expansion due to economic growth in the world. Simultaneously, the requirements for substation equipment compactness, cost reduction and efficiency also have been emphasized in the competitive market. This paper introduces several examples of recent developments on the compact and reliable...
