Sensitivity mapping informs mitigation of bird mortality by collision with high-voltage power lines
Mapping the relative risk of impact on nature by a human infrastructure at landscape scale (“sensitivity mapping”) is an essential tool for minimising future new development or prioritising mitigation existing impacts. High-voltage power lines (“transmission lines”) are known to increase bird mortality collision. Here we present method derive high resolution map transmission line impacts across...
The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...
Nowadays high-voltage power sources is used in different areas such as generation of atmospheric-pressure plasma. Different voltage waveforms affect the plasma generation and its quality. In this paper a new high voltage square wave with DC-offset power source is presented to study the different parameters on plasma generation and propagation. The proposed converter which is based on power semi...
Although the trend toward finer geometries and larger chips has produced faster systems, it has also created larger voltage drops and higher current densities in chip power supply networks. Excessive voltage drops in the power supply lines cause incorrect circuit operation, and high current densities lead to circuit failure via electromigration. Analyzing this power supply noise by hand for lar...
Power distribution feeders contains many laterals, sub-laterals, different number of circuit line, load taps, balanced and unbalanced load, different type of lines (cable or overhead), different cross-sections and numerous distribution transformers with different capacities. Moreover, the voltage and current are measured only at the beginning of the feeder. Thus, fault location is very complex....
