Temperature and stress induced linear birefringence in the sensing material causes error and instability. In order to properly apply Eq 2 in the MOCT design by making the optical path wrap around the current carrying conductor, the optical path has to be folded by reflections. We think you have liked this presentation. With over 30, presentation design templates to choose from, CrystalGraphics offers more professionally-designed s and templates with stylish backgrounds and designer layouts than anyone else in the world.
And, best of all, most of its cool features are free and easy to use. The Optical isolator market analysis is provided for the international markets including development trends, competitive landscape analysis, and key regions development status.
They are all artistically enhanced with visually stunning color, shadow and lighting effects. 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. Electromagnetic Flowmeter Why use flow meters What is a magnetic flow meter — How do they work — How are the different from other meters Items that will.
For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. A polarizer is used to convert the randomly polarized incident light into linearly polarized light. Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free.
No need to break the conductor to enclose the optical path in the current carrying circuit.
Electric current path of primary bus has to be designed properly to minimize the mechanical forces. The sensor head consists of optical components. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown.

Pawan Janorkar 01 July This has required the use of an auxiliary current transformer or optical isolator to avoid such problems. 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. IEEE transactions on power delivery ,vol.
Do you have PowerPoint slides to share? Phase shift should be avoided. A polarizer is used to convert the randomly polarized incident light into linearly polarized light. No need to use metallic wires to transfer the signal and so simpler insulation structure than conventional current transformer.
Sensor head located near the current carrying conductor. Therefore the insulation structure of an MOCT is simpler than that of a conventional current transformer, and there is no risk of fire or explosion by the MOCT.

Signal Processing Unit basically converts the optical signal into suitable electrical form. Ucrrent purpose of using the analyzer is that photo detectors can only detect the intensity of light, rather than the orientation of polarizations.
It consist of a sensor head located near the current carrying conductor, an electronic signal processing unit and fiber optical cables linking to these two parts.
It rejects the magnetic field signals due to external currents which are normally quite strong in power system. High immunity to electromagnetic interference. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown.

This study focuses on Chinas Fiber Optics Industry assessments and company profiles. About project SlidePlayer Terms of Service. The polarization compensation technique is applied at each tranformer of the prisms, so that the light passing through the prism remains linearly polarized.
For a small fee you can get the industry’s best online privacy or publicly promote your presentations and slide shows with top rankings. It appears that the newly emerged Magneto-optical current transformer technology provides a solution for many of the above mentioned problems. In addition to the insulation benefits, a MOCT is able to provide high immunity to electromagnetic interferences, wider frequency response, large dynamic range and low outputs which are compatible with the inputs of analog to digital converters.
Our new CrystalGraphics Chart and Diagram Slides for PowerPoint is a collection of over impressively designed data-driven chart and editable diagram s guaranteed to impress any audience. The electric current path of the primary bus has to be designed properly to minimize the mechanical forces on the primary magnetp-optical for through faults.
This has required the use of an auxiliary current transformer or optical isolator to avoid such problems. These Key players compete based upon pricing, quality, Technology and reputation.
