Current and Voltage Response Measurements on Nanodielectrics
2020 IEEE 3rd International Conference on Dielectrics (ICD), 2020Dielectric materials are an essential part of all electrical devices. One of the reasons, their properties are studied, is that they are most impacted by internal and external influences during the lifetime of the electrical device. Composite materials are commonly used as a dielectric part, because of the synergy effect, when combining various ...

An all-digital voltage sensor for static voltage drop measurements
2016 IEEE Sensors Applications Symposium (SAS), 2016One of the main challenges in semiconductor industry is the variability in devices and circuit parameters which will harm the performance and the energy efficiency of the circuit. In addition, voltage fluctuation also makes the performance of the design unpredictable.

Nature, 1945
ABSOLUTE measurements of high voltages, up to about 300 kilovolts, have been carried out by various workers using instruments of the attracted disk type, as originally devised by Lord Kelvin, in which the electrostatic deflecting force on the disk is balanced by mechanical means.

Ultrafast pulses can be measured by a resistive divider or a capacitive divider (Sect. 17.1). In terms of the ease of construction and characterization, the resistive divider is a better choice. The divider is typically consisted of a high value resistor and a 50 Ω resistor, designed to match the impedance of a standard coaxial cable. The configuration

Fault Location Using Voltage Measurements
IEEE Power Engineering Review, 2001This paper presents a novel method for locating short-circuit faults in electric power systems. The origins of the method are in the concept of vulnerability contours, which is used in assessing the likelihood of voltage sags effecting a given network area. The method is applied in an off-line step and an on-line step.

Accurate Voltage Measurement by the Quadrature Method
IEEE Power Engineering Review, 2002This paper introduces the quadrature method for measuring voltage using one or more electric field sensors. To date, all high-voltage sensors, from conventional inductive transformers to modern optical voltage transducers, have one or more of the following traits in common: large size and weight, high-voltage electrodes in close proximity, expensive ...

14th IEE Microwave Measurements Training Course, 2005
The majority of signal amplitude or level measurements made at RF and microwave frequencies are measurements of power rather than voltage. Voltage measuring instruments such as RF millivoltmeters are still in frequent use but are nowadays less common than in the past.

Field Measurements Of Touch And Step Voltages
IEEE Transactions on Power Apparatus and Systems, 1984This paper presents the study of a measurement technique for touch and step voltages and the results of measurements obtained inside and outside substations. Details of a low-voltage and a highvoltage method of current injection are given. Setups for measuring the shock touch voltage and shock step voltage are characterized, in which the effect of foot
