In this paper studies of overvoltage and capacitance measurements at silver cathodes in aqueous perchloric acid at room temperature are described. Capacitances were deduced from open-circuit potential decay measurements. The increase of overvoltage and the growth of the measured capacitances in the course of electrolysis are attributed to a growing pseudocapacitance component. This is anal...

In low-voltage power networks with a large share of distributed energy sources, the phenomenon overvoltage is increasingly observed. Although it may be desirable to raise voltage value downstream network, in some cases upper allowable limit exceeded. The method eliminating rises commonly used Polish system installation protections, disconnecting source from grid. Such action reduces profitabili...

The biggest loss in the industry that caused to experience financial losses should have been target of achieving 90% - 100% production was a decrease up 40%, due machines not running excessive loads used resulting overvoltage disturbances, voltage drops or unbalanced voltages. To overcome monitoring tool and protection system are needed with method can cut off load automatically when disturbanc...

Residential rooftop-mounted solar photovoltaic (PV) panels are being installed at an increasing rate, both in New Zealand and globally. There have been concerns over possible issues such as overvoltage and overcurrent. These PV systems are mostly connected at low voltage (LV). This study presents a case study of simulating the entire LV network from a single utility, comprising 10,558 11 kV–415...

High-speed EMUs (electric multiple-units) frequently pass through the phase-separation zone during operation. Overvoltage generated operation of vehicle-mounted circuit breaker has a long duration and high waveform steepness, which accelerates service life equipment is likely to cause insulation failures. For above-mentioned problems, operating overvoltage characteristics high-speed EMU were ob...
