Voltage Balance and Energy Balance in an Electrolytic Cell

1985
Electrolytic current will flow from the anode to the cathode in electrolytic solution in a cell by means of transport of both cations and anions to the respective directions of the electric field. The mechanism of conduction in electrolytic solution differs from that in a metallic conductor in which free electrons move in the inverse direction of flow ...

The Voltage Balance in the Mercury Cell

Journal of The Electrochemical Society, 1950
The distribution of voltage drop through a mercury cell has been calculated and directly measured at different current densities in an industrial de Nora cell which is described. The cell was operated at constant temperature and fed with 305 g/l sodium chloride solution at a rate proportional to current density.

Progress in measurements with the ETF voltage balance

IEEE Transactions on Instrumentation and Measurement, 1993
The results of two series of measurements with the ETF-84 voltage balance carried out in 1987 and 1988, using the classical method of weighting, were previously presented by the authors (1988) with the proviso that some systematic errors had not been accounted for.

Voltage balancing using switched capacitors

Electric Power Systems Research, 1992
Thyristor switched capacitors (TSCs) are a useful means of load balancing and reactive power support. The control of a general load by a binary weighted switched capacitor system is discussed in this paper along with a simple control scheme where the capacitor bank across a line pair is adjusted to control the fundamental voltage magnitude for that ...

A Self-Balancing High-Voltage Capacitance Bridge

IEEE Transactions on Instrumentation and Measurement, 1964
A self-balancing high-voltage capacitance ratio bridge, especially designed for continuous measurement of corona losses on experimental transmission lines, is described. The instrument is derived by combining a negative-feedback amplifier with a high-voltage capacitance bridge based on the current comparator principle.

Reactive Power Balance and Voltage Control

1997
Economic considerations have generally resulted in short-term generation unit commitment practices and trading procedures placing considerable emphasis on scheduling active power to meet system demands. Voltage control is usually managed as a second step in the operation of the power system.

A comparison of voltage balancing versus energy balancing approach for modular multilevel converters

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
The multilevel submodules (SMs) bring the added advantages of compact size and improved efficiency over standard submodules to the modular multilevel converter (MMC). These SMs have more than one floating capacitor, which stores the arm energy. Each arm of MMC has several SMs connected in series to meet the required operating voltage. The SM capacitors

Grounding banks for balancing feeder voltages

Electrical Engineering, 1951
DISTRIBUTION engineers, seeking means to provide a better balance of neutral voltage on 3-phase feeders, have suggested the use of grounding banks at one or more points along the feeder. The term 'grounding bank' is used here to mean a Y-delta transformer bank, the Y side tapped from the feeder with the Y neutral connected to the system neutral ...

Determination of the Volt by Means of Voltage Balances

Metrologia, 1988
The determination of the value of 2e/h by means of voltage balances in the institutions: LCIE, PTB, CSIRO and ETF in Zagreb, is discussed. The construction of the balances is described. The measurement results achieved, as well as their expected and obtained partial and total measuring uncertainties, are reviewed.

Voltage Recovery after Unbalanced and Balanced Voltage Dip in Three-Phase Systems

IEEE Power Engineering Review, 2002
This paper studies the recovery of the voltage after a voltage dip due to a fault in a three-phase system. The instant of voltage recovery corresponds to the instant of fault clearing. For single-phase and phase-to-phase faults, a single point-on-wave of voltage recovery can be defined. For two-phase-to-ground and three-phase faults, the recovery takes
