These Key players compete based upon pricing, quality, Technology and reputation. As no metallic wires are needed therefore it provides better insulation. 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. A polarizer is used to convert the randomly polarized incident light into linearly polarized light.

MOCT(MAGNETO OPTICAL CURRENT TRANSFORMER) – PowerPoint PPT Presentation

Describe the components of an ideal transformer. To make this website work, we log user data and share it with processors.

They are used for mechanical coupling and the aligning of core fibers to allow efficient transfer of light while providing high reliability, high return loss and low insertion loss.

Magneto Transfodmer Current Transformer 5 months ago. 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.

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

The concept of Faraday Effect could be understood from the Fig.

Provides no Electromagnetic Interference. There is truly something for everyone! Proper wrapping of optical path around current carrying conductor is required.

The optical design enables accurate measurement of fault currents. OK Introduction to Power Supplies. 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.

PowerPoint Templates – Are you a PowerPoint presenter looking to impress your audience with professional layouts? High immunity to Electromagnetic interferences. Phase shift should be avoided. 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. Stimulation results include information such as polarization state change at each reflection and the overall responsibility of the optical sensor.

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. IEEE transactions on power delivery ,vol. It fulfills the two purposes-metering and relaying. An accurate electric current transducer is a key component of any power system instrumentation. 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 etc.

Click to allow Flash. 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.

For transormer voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation joct the primary bus and the secondary windings. 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.

This has required the use of an auxiliary current transformer or optical isolator to avoid such problems. Magneto Optics Current Transformer. Related More from user. Quite new technology-in research stage. 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.

MOCT technology provides solution to many of the problems of magneto-opitcal current transformer. An accurate electric current transducer is a key component of any power system instrumentation. The sensor head consists of optical components. Sensor head located near the current carrying conductor. Inductive type transformer with core and
