When a transformer is energized the phenomenon of magnetizing inrush current occurs and causes a pseudo tripping signal to the differential relay which leads to the problem of mal operation or false tripping of the relay. In order to avoid this false tripping of the differential relay and for safe operation of the transformer the distinction of inrush current with internal fault current is very...
Low-power memories typically operate in the subthreshold region of device; however, as supply voltage continues to decrease, impact leakage current on SRAM stability becomes more significant. The traditional method measuring static noise tolerance only considers effect voltage, and measurement results are not accurate enough. Therefore, this paper proposes a leakage-current-based analysis that ...
Thepurpose of this study was to determine the link between induction voltages from various electrical loads. We used a residual current device (RCD) circuit that operates with capacitor as DC voltage reading tool. The reads value o
There are three major sources of leakage current today, namely the sub-threshold leakage, gate leakage and the reverse biased junction band-to-band-tunneling leakage. These currents depend on the logic state of a CMOS circuit as determined by input pattern. Consequently, there exists a pattern that will produce the highest leakage current. Previously, researchers have investigated the problem o...
Electrical insulation is an important part of all electrical systems. The level of insulation safety provided by an insulator depends on the amount of leakage current flowing on its surface. Actually increased leakage current causes a part of high voltage to appear at dead end of insulator. This voltage may sometimes be of order of 1000 to 5000 Volts depending upon weather conditions. Such a le...
