The residual voltage in fast electrophotography of a-SiHx
Solar Energy Materials, 1982Abstract The space charge distribution in a-SiH x photoreceptors is investigated by measurement of the residual voltage in xerographic photodischarge characteristics. The correlation between boron concentrations in the a-SiH x photoreceptor and the residual voltage is evaluated.

Residual Voltages and Currents in Power Systems
Transactions of the American Institute of Electrical Engineers, 1928In the problem of inductive coordination of power and communication systems, residual voltages and currents in the power lines are an important element, yet it is apparent that they are not in general well understood, Studies have been made and others are under way by well-equipped organizations, which will add much to the data concerning them.

Residual harmonics in voltage unbalanced power systems
Industry Applications Society 40th Annual Petroleum and Chemical Industry Conference, 1994The analysis of residual harmonics requires combining linear and nonlinear analysis into a computer algorithm. The mathematical techniques are to apply state space methods to solve the nonlinear loads such as converters in a time domain format, analyze the resulting waveform with a Fourier analysis to convert the data to the frequency domain, and then ...

A Theoretical Investigation of the Residual Voltage on Electrophotographic Plates
Japanese Journal of Applied Physics, 1982A numerical analysis of the residual voltage on an electrophotographic plate is presented for a photodischarge process characterized by carrier trapping and release parameters. The physical model is described by a set of one-dimensional transport equations with appropriate initial and boundary conditions.

Enhancement of the SPD Residual Voltage at Apparatus Terminals in Low-Voltage Power Systems
IEEE Transactions on Power Delivery, 2007Surge protective devices (SPDs) are installed at the boundaries of lightning protection zones to damp the surges to the protection level of the SPD. If the circuit between the SPD and the apparatus to be protected is too long, the propagation of the surges leads to oscillation phenomenon.

Measurement and calculation of surge-arrester residual voltages
Measurement, 2011Abstract This paper presents accurate measurement of residual voltages of surge arresters (SA) by two designed charge meters (D-dot probes) as well as simulation validation in the high-conduction regime. Simultaneous impulse voltage measurements were conducted by using two D-dot probes, two uncompensated commercial mixed resistive–capacitive (RC ...

Conference on Electrical Insulation and Dielectric Phenomena, 2003
An approach is developed which can be used to calculate the sparking and residual voltages V/sub s/ and V/sub r/, or the ratio between them, from the corner values V/sub p/ and V/sub q/ in a parallelogram. From a theoretical analysis of the parallelogram method, which is used for partial-discharge measurement, the width of the parallelogram is equal to
