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.
To make this website work, we log user data and share it with processors. 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.
Optical Imaging Market Key Players – However, high transforker and installation costs and reimbursement issues are expected to restrict the growth of this market.

Magneto-Optical Current Transformer Technology MOCT | Seminar Report, PPT, PDF for ECE Students
A polarizer is used to convert the randomly polarized incident light into linearly polarized light. The accuracy of MOCT is so far insufficient for the use in power systems. This magneto optical current transducer eliminates many of the drawbacks of the conventional current transformers. No need to use metallic wires to transfer the signal and so simpler insulation structure than conventional current transformer. 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.
Stimulation results include information such currennt polarization state change at each reflection and the overall responsibility of the optical sensor. Prisms should be designed to keep the light linearly polarized. Additionally, they are used for termination of cables. Michael Faraday koct 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.
Temperature and stress induced linear birefringence in the sensing material causes error and instability. 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.
This study focuses on Chinas Fiber Optics Industry assessments and company profiles. Passive optical current transducer which uses light to accurately measure current on high voltage systems. An intermediate stage, which is called the signal magneto-optival.
This MOCT is widely used in power systems and substations nowadays. The sensor head consists of optical components. We think you have liked this presentation.

Chart and Diagram Slides for PowerPoint – Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. Provides no Electromagnetic Interference. Sensor head located near the current carrying conductor. Moreover, manufacturers mainly ensure to deliver the best quality products based on innovative technologies, and best practices.
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. These Key players compete based upon pricing, quality, Technology and reputation. The Optical isolator market analysis is provided for the international markets including development trends, competitive landscape analysis, and key regions development status.
The purpose of using the analyzer is that photo detectors can only detect the intensity of light, rather than the orientation of polarizations.
