Current Transformer Burden and Saturation

IEEE Transactions on Industry Applications, 1979
A tutorial review of the steady-state and transient behavior of current transformers used with power system relays and meters is presented. ANSI accuracy standards are discussed and consideration is given to the significance of burden and saturation in the application of protective relays.

Saturation Electron Current in a Magnetic Field

Japanese Journal of Applied Physics, 1968
In connection with the saturation electron current of a disk probe in a magnetic field, quantitative comparisons of experimental results with theoretical results are made for the large ratio of the electron mean free path λ e to the Debye length λ D , 102∼103.

On the Threshold of Current Saturation in GaAs

Japanese Journal of Applied Physics, 1967
Current saturation inn-GaAs was investigated between 77°K and room temperature. Measurements were made of the dependences of the threshold electric field of saturation and the saturation drift velocity both on temperature and carrier concentration.

Plasma Heating by Current-Saturation

Nature, 1959
SEVERAL attempts have been made (for example in Zeta 1, Sceptre 2, Perhapstron 3, etc.) to produce high-temperature plasma in a toroidal discharge by means of large induced currents. These experiments have shown that Joule-heating of the plasma by the induced electron current is inefficient.

Estimation of the primary current in a saturated transformer

[1991] Proceedings of the 30th IEEE Conference on Decision and Control, 2002
It is pointed out that, when a current in a power system is measured using a transformer, the measurement can be distorted by transformer saturation. The authors examine two methods of estimating the primary current from the secondary in the presence of saturation.

Eddy-current losses in saturated cylinders

IEEE Transactions on Communication and Electronics, 1964
This paper discusses the process of magnetization and the eddy-current losses in saturated cylinders subjected to a sinusoidal magnetic field. Maxwell's equations are solved in cylindrical co-ordinates for an assumed magnetization curve B = B s sign H.

Temperature dependence of the saturation current of MOST's

IEEE Transactions on Electron Devices, 1968
The saturation current of n -enhancement silicon MOST's has been investigated as function of temperature. The results are in reasonable agreement with a simple theoretical expression which takes into account the field dependence of electron mobility.

CURRENT SATURATION AND PHOTOFERROELECTRIC EFFECT IN SbSI

Applied Physics Letters, 1967
The illumination of the ferroelectric SbSI in the spectral region where a maximum of photoconductivity of this crystal took place (λ ≃ 6200 Å) decreased the ferroelectric polarization. This resulted in the appearance of a region of saturation of the V-I characteristic and in the decrease of the pyrocurrent, being measured in the phase transition.

Saturation Ion Currents to Langmuir Probes

Journal of Applied Physics, 1965
The parabolic variation of saturation ion current with probe potential observed in dense plasmas is fortuitous and is not directly related to the effects of orbital motion. Agreement between measured and computed saturation ion characteristics is illustrated.

On parametric excitation with current saturable inductances

Journal of the Franklin Institute, 1960
Abstract A parametric amplifier circuit is described. The nonlinearity involved is an abrupt one and a method of analysis of “relaxation oscillations” is preferred to techniques assuming quasi-linearity. This leads to a physical understanding of the cycle of oscillations as well as quantitative relationships which are helpful to the designer.
