Request Sample of this report https: Click to allow Flash. But aside from that it’s free. Total internal reflections and metal reflections are good ways to achieve this. 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.

Fiber Optical Cables linking these two parts. It appears that the newly emerged Magneto-optical current transformer technology provides a solution for many of the above mentioned problems.

The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown.

Curgent MOCT is widely used in power systems and substations nowadays. Mict voltage transducers EOVT Registration Forgot your password? This has required the use of an auxiliary current transformer or optical isolator to avoid such problems.

Analyzer converts the orientation variation of polarized light into intensity variation with two outputs. 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.

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.

Stimulation results include information such as polarization state change at each reflection and the overall responsibility of the optical sensor. Many of them are also animated. You can use PowerShow. Pawan Janorkar 01 July Electromagnetic Flowmeter Why use flow meters What is a magnetic flow meter — How do they work — How magneho-optical the different from other meters Items that will.


And their quality is top notch. The Optical isolator market analysis is provided for the international markets including development trends, competitive landscape analysis, and key regions development status.

Magneto Optics Current Transformer

In an conventional current transformers, there is a chance of saturation of magnetic field under high current, complicated insulation and cooling structure, a chance of electro magnetic interference. 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. 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.

To measure currents, power stations and substations conventionally employ inductive type current transformers with core and windings.

Optical Imaging Market Key Players – However, high investment and installation costs and reimbursement issues are expected to restrict the growth of this market.

We’ll even convert your presentations and slide shows into the universal Flash format with magneyo-optical their original multimedia glory, including animation, 2D and 3D transition effects, embedded music or other audio, or even video embedded in slides. Sensor head located near the tchnology carrying conductor.

They are ideal for the interference between power systems and computer systems. Prisms should be designed to keep the light linearly polarized. Moreover, manufacturers mainly ensure to deliver the best quality products based on innovative technologies, and best practices.

OK Introduction to Power Supplies. There is truly something for everyone! The signal is brought down to signal processing unit by means optical fiber cables. However, Asia Pacific is anticipated to experience significant growth with rising incidences of cancer and other diseases.

A polarizer is used to convert the randomly polarized incident light into linearly polarized light. 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. Additionally, they are used for termination of cables. High immunity to Electromagnetic interferences. In an conventional current transformers, there is a chance of saturation of magnetic field under high current, complicated insulation and transfoormer structure, a chance of electro magnetic interference etc.

They are all artistically enhanced with visually stunning color, shadow and lighting effects. Temperature and stress induced linear birefringence in the sensing material causes error and instability. It meets the protection class accuracy as specified by IEC An accurate technllogy current transducer is a key component of any power system instrumentation. 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.

Low voltage outputs which are compatible with the inputs of digital to analog converters. Quite new technology-in research stage.

Magneto Optics Current Transformer 5 months ago. Electric current path of primary bus has to be designed properly to minimize the mechanical forces. 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.
