Abstract:

High voltages of alternative current (AC) are important because they are needed for numerous applications in physics and engineering. High AC voltages are also used to test insulating materials for their dielectric properties. Calibrations of instruments for high-voltage measurements should provide metrological traceability to national standards. This applies to the requirements for both voltage measuring instruments and current measuring instruments. The transformer for high-voltage measurements is used to reduce the values of currents and voltages during measurements in high-voltage electric

Abstract:

We present the design and implementation of a measurement system that enables parallel drive and detection of small currents and voltages at numerous electrical contacts to a multi-terminal electrical device. This system, which we term a feedback lock-in, combines digital control-loop feedback with software-defined lock-in measurements to dynamically source currents and measure small, pre-amplified potentials. The effective input impedance of each current/voltage probe can be set via software, permitting any given contact to behave as an open-circuit voltage lead or as a virtually grounded cur

Abstract:

The resonant-column test is one of the most common procedures for dynamic characterization of soils (American Society for Testing and Materials standard). The test procedures require the measurement of the current flowing through the driving coils. In many cases, however, the input voltage has been measured and the results analyzed as a traditional current measurement. In this paper, the difference between current and voltage measurements is clarified; specifically, a new transfer function is presented for the analysis of data when the input voltage is measured. The new model is evaluated by t

The difference between them is the harmonic distortion energy that causes extra losses to the electric networks. The voltage harmonic distortions at the measurement point exceed the nor

Patch clamping is a gold-standard electrophysiology technique that has the temporal resolution and signal-to-noise ratio capable of reporting single ion channel currents, as well as electrical activity of excitable single cells.

This has limited the scalability and throughput of patch clamping for single-ion channel and single-cell analyses. In this work, we have developed a custom patch-clamp amplifier microchip that can be fabricated using standard commercial silicon process

Abstract:

This paper deals with voltage unbalances and how they can be quantified according to the standards. Firstly, a comparison between the different unbalance voltage factors is conducted in order to remark on their divergences. Secondly, according to the standard that better represents the phenomenon, i.e., EN 50160, a new methodology is proposed to quantify the voltage unbalance factor (VUF). In order to do so, it is recommended to measure the voltage unbalance in three-phase installations by means of a new smart sensor based on a single voltage sensor, which measures the direct-current (DC) volt

Electric motors with DC voltages that are often used today are less effective and efficient because of the use of brushes that will run out when used. To overcome the weaknesses of this DC motor, then used Brushless Direct current Motor (MASTS). MASTS is a three phase AC motor. In a fixed application, a three phase AC voltage source can be used directly. In a mobile application, it takes an AC voltage sourced from a DC voltage. For this reason, an inverter is designed to convert DC voltage into three phase AC. The meth

The results of actual measurements on p-channel MOSFETs are reported that confirm the validity and the significance of the proposed approach.

Abstract:

The article is devoted to the results of research of metrological characteristics of the newly created State primary standard of the unit of scaling factor of alternating current (AC) voltage up to 750/√3 kV. Until 2019, there was no metrological support for ultra-high voltage measurements in Ukraine. From 2016 to 2019, the State Enterprise "Ukrmetrteststandard" carried out research work on the development of the state primary standard unit of scaling factor of AC for ultra-high voltage. The created standard became the basis for metrological support of measurement of ultrahigh voltages of alte

Abstract:

The study of electronics, motors and mechanical noise and vibration have often been treated as separate fields in R&D, Production, and test/validation. In electric powertrains, the electric and mechanical must be designed and tested in parallel to really understand the machine operation. This paper will highlight an existing link between the electrical and mechanical noise in electric powertrains and what measurement/analysis tools are available for performing an NVH analysis including electrical measurements.

Abstract:

In this paper, current-voltage (i-Vg) results from different kinds of n-type InP Schottky diodes are reported. The diodes were fabricated on an unintentionally doped n-type (100) indium phosphide substrate, and the i-Vg characteristics were measured in the temperature range 100 300 K. For the ideality factor, n always exhibited a small (1) but continuous increase with the voltage. At higher forward voltage, slightly higher values of n were due to series resistance effect; in other words, the interface state density always remained small. However, it was possible to obtain some information in

Full text

Abstract:

Large steam turbine generators are increasingly vulnerable to damage from shaft voltages and bearing currents due to the widespread adoption of modern power electronic excitation systems and more flexible operating regimes. Earthing brushes provide a critical path for discharging these shaft currents and voltages, but their effectiveness depends on the timely detection of brush degradation or faults. Conventional monitoring of shaft voltage and current is often rudimentary, typically limited to peak readings, making it challenging to identify specific fault conditions before mechanical damage

Abstract:

Abstract Charge transport measurements in compressed bulk graphene oxide (GO) have been studied within the temperature range 15-450 K. Structural properties and surface morphologies of the bulk compressed GO were studied using X-ray diffraction and transmission electron microscopy. Raman and X-ray photoelectron spectroscopies were also used to confirm the presence of graphitic phases and the various functional groups in the GO, respectively. Current-voltage characteristics of the GO measured with gold (Au) electrodes at different temperatures showed no Schottky barrier at the Au/GO interface.

Full text

Abstract:

In this paper, the effects of inaccurate DC bus voltage measurement are analyzed to model predictive current-controlled permanent magnet synchronous motor (PMSM) drives. It is found that the selection of the optimal space vector is affected by inaccurate DC bus voltage measurements, and the shortest distance principle is proposed to evaluate the effects. With the under-voltage measurement, the actual q axis current is always larger than the reference value, and PMSM may be damaged by the over-current phenomenon. However, the actual q axis current is always smaller than the reference value with

Abstract:

We propose the simultaneous measurement of a displacement current and current density‐voltage‐luminance (DC‐JVL). We measured RGB OLED samples and obtained differences between onset voltages of current increase and emission voltages in low current density regions. We also confirmed that the DC‐JVL has higher sensitivity than the conventional JVL from the measurement of current efficiency vs. current density characteristics.
