Optical Imaging Market Key Players – However, high investment and installation costs and reimbursement issues are expected to restrict the growth of this market. 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 msgneto-optical direction of optical path.
To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. The sensor head consist of only optical component such as fiber optical cables, lenses, polarizers, glass prisms, mirrors etc.

You can choose whether to allow people to download your original PowerPoint presentations and photo slideshows for a fee or free or not at all. Published by Marilynn Young Modified over 3 years ago. This MOCT is widely used in power systems and substations nowadays. Provides no Electromagnetic Interference. Prisms should be designed to keep the light linearly polarized.

Phase shift should be avoided. Products Amgneto-optical on our sister site CrystalGraphics. Michael Faraday discovered that the orientation of linearly polarized The MOCT measures the rotation angle caused by the magnetic field and converts it into a signal of few volts proportional to the electric currant. The electric current path of the primary bus has to be designed properly to minimize the mechanical forces on the primary conductors for through faults. Stimulation results include information such as polarization state change at each reflection and the overall responsibility of the optical sensor.

Signal Processing Unit basically converts the optical signal into suitable electrical form. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown.
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. No need to use metallic wires to transfer the signal currnet so simpler insulation structure than conventional current transformer.

This magneto optical current transducer eliminates many of the drawbacks of the conventional current transformers. Michael Faraday discovered that the orientation of linearly polarized light was rotated under the influence of 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.
Magneto Optics Current Transformer 5 months ago. J C Santos ,M. 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.
Many of them are also animated. The optical prism has to be designed to keep the light going through the MOCT linearly polarized.

The report provides a basic overview of the industry including definitions, classifications, applications and industry chain structure. Do you have PowerPoint slides to share? In addition to the concerns, with the computer control techniques and digital protection devices being introduced into power systems, the conventional current transformers have caused further difficulties, as they are likely to introduce electro-magnetic interference through the ground loop into the digital systems.
The design approach is to redefine the interface point as to input the analog to transfformer conversion function used by each of these measurement systems.

A detector- transducing or sensor-transducer stage Stage 2: The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown. It meets the protection class accuracy as specified by IEC The outputs are send to photo detectors.
However reflections introduce phase shift; hence change the polarization state of the light. An accurate electric current transducer is a key component of any power system instrumentation. For a small fee you can get the industry’s best online privacy or publicly promote your presentations and slide shows with top rankings.
Total internal reflections and metal reflections are good ways to achieve this. Therefore the insulation structure transformwr an MOCT is simpler than that of a conventional current transformer, and there is no risk of fire or explosion by the MOCT. The output optical signals from the analyzer can be described as.
