Magneto Optics Current Transformer
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.
An accurate electric current transducer is a key component of any power system instrumentation. Global Distribution Transformer Market Traansformer Report – Forecast to – Distribution Transformer market appears to be competitive with the presence of several large and small players operating in the Distribution Transformer Market. Restricted by production technology, most manufacturers are concentrated in Japan, the United States and Europe, while other countries mainly produce optical fiber and cable through imports of optical fiber preform.
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. The purpose of using the analyzer is that photo detectors can only detect the intensity of light, transformeer than the orientation of polarizations.
This has required the use of an auxiliary current transformer or optical isolator to avoid such problems. 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.

No need to break the conductor to enclose the optical path in the current carrying circuit. 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.
Analyzer converts the orientation variation of polarized light into intensity variation with two outputs. A polarizer is used to convert the randomly polarized incident light into linearly polarized light.
Distribution Transformer market demonstrates a high growth potential which is likely to attract many entrants to the market resulting in to intensified competition further. Many of them are also animated. Products Sold on our sister site CrystalGraphics.
Whether your application is business, how-to, education, medicine, school, church, sales, marketing, online training or just for fun, PowerShow. Low voltage outputs which are compatible with the inputs of digital to analog converters.
Additionally, they are used for termination of cables. This MOCT is widely used in power systems and substations nowadays. 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. View by Category Toggle navigation. The signal is brought down to signal processing unit by means optical fiber cables.
Electric current path of primary bus has to be designed properly to minimize the mechanical forces.
Magneto-Optical Current Transformer Technology MOCT | Seminar Report, PPT, PDF for ECE Students
Transformers are designated to be most efficient when operated at full rated 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. Magneto-optic current transducers MOCT.
Most suited for outdoor type applications. And, best of all, most of its cool features are free and easy to use. In an conventional transgormer 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.
Passive optical current transducer which uses light to accurately measure current on high voltage systems. C Taplama Ciogle and K Hidak?
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. Don’t enter email or mobile no.
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. Magneto Optics Current Transformer 5 months ago. 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.
And a new trend is being introduced, which known as OCP based on adaptive theory, 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 insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdown. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. To make this website work, we log user data and share it with processors.
They are ideal for the interference between power systems and computer systems. Inductive type transformer with core and The dramatic expansions of the manufacturing capabilities and rising consumer consumptions in China have transformed Chinas society and economy.
