Magneto Optics Current Transformer

VI I current to be measured,? To view this presentation, you’ll need to allow Flash. We’ll even convert your presentations and slide shows into the universal Flash format with all their original multimedia glory, including animation, 2D and 3D transition effects, embedded music or other audio, or even video embedded in slides. Many of them are also animated.

This study focuses on Chinas Fiber Optics Industry assessments and company profiles. The polarization compensation technique is applied at each corner of the prisms, so that the light passing through the prism remains linearly polarized.

The design approach is to redefine the interface point as to input the analog to digital conversion function used by each of these measurement systems. A polarizer is used to convert the randomly polarized incident light into linearly polarized light.

The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown. Michael Faraday discovered that the orientation of linearly polarized light was rotated under the influence transforjer the magnetic field when the light propagated in a piece of glass, and the rotation angle was proportional to the intensity of the magnetic field.


Electro-optic voltage transducers EOVT In order to properly apply Eq magnto-optical in the MOCT design by making the optical path wrap around the current carrying conductor, the optical path has to be folded by reflections. As no metallic wires are needed therefore it provides better insulation. Request Sample of this report https: About project Magneto-oltical Terms of Service. The Faraday Effect is the phenomenon that the orientation of polarized light rotates under the influence of the magnetic fields and the rotation angle is proportional to the strength of the magnetic field component in the direction of optical path.

There is truly something for everyone!

And a new trend is being introduced, which known as OCP based on adaptive theory, which make use of accuracy in the steady state of the conventional current transformer and the MOCT with no saturation under fault current transients.

Electric current path of primary bus has to be designed properly to minimize the mechanical forces.

Then another polarization prism is used as an analyzer, which is 45 0 oriented with the polarizer, to convert the orientation variation of the polarized light into intensity variation of the light with two outputs, and then these two outputs are send to photo detectors.


The reliability of conventional high-voltage current transformers have been questioned because of their violent destructive failures which caused fires and impact damage to adjacent apparatus in the switchyards, electric damage to relays, and power service disruptions. With short circuit capabilities of power systems getting larger, and the voltage levels going higher the conventional current transformers becomes more and more bulky and costly also the saturation of the iron core under fault current and the low frequency response make it difficult to obtain accurate current signals under power system transient conditions.

In order to stimulate the behavior of the polarized light reflect through the glass prism of an MOCT, ie to maintain the light traveling through the glass prism to be linearly polarized and also for the analysis of the effects of dielectric and metal reflections on the linearly polarized light, a computer programme is written in FORTARN language. It rejects the magnetic field signals due to external currents which are normally quite strong in power system.

The outputs are send to photo detectors. The Optical isolator market analysis is provided for the international markets including development trends, competitive landscape analysis, and key regions development status. It meets the protection class accuracy as specified by IEC The report provides a basic overview of the industry including definitions, classifications, applications and industry chain structure.

The optical prism has to be designed to keep the light going through the MOCT linearly polarized.
