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. The output optical signals from the analyzer can be described as. My presentations Profile Feedback Log out. Magneto-optic current transducers MOCT.

Pawan Janorkar 01 July Total internal reflections and metal reflections are good ways to achieve this. Provides no Electromagnetic Interference. Passive optical current transducer which uses light to accurately measure current on high motc systems. Combination of magnetic and electronics have led to tecnology development of spintronics, that has created MRAM memory with characteristics of non-volatile, high density, radiation hardness, high endurance and high speed operations.

Therefore the insulation structure of an MOCT is simpler than that of a conventional current transformer, and there is no risk of fire or explosion by the MOCT. Don’t enter email or mobile no. Low voltage outputs-compatible with the inputs of digital to analog converters. We think you have liked this presentation.

MOCT technology provides solution to many of the problems of conventional current transformer. It rejects the magnetic field signals due to external currents which are normally magneto-opticl strong in power system. This has required the use of an auxiliary current transformer or optical isolator to avoid such problems.

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. These Key players compete based upon pricing, quality, Technology and reputation. The concept of Faraday Effect could be understood from the Fig.


The optical prism has to be designed to keep the light going through the MOCT linearly polarized. 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.

Magneto-opfical and Diagram Slides for PowerPoint – Beautifully designed chart and diagram s for PowerPoint with visually stunning graphics and animation effects. 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.

No need to break the conductor transfodmer enclose the optical path in the current carrying circuit.

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. 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.

The Faraday effect outlined in eq 2 is a better format to apply to an MOCT, because the rotation angle in this case is directly related to the enclosed electric current.

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.

Polarization is a property of certain types of waves that describes the orientation of their oscillations. Distribution Transformer market demonstrates a high growth potential which is likely to attract many entrants to the market resulting in to intensified competition further.

An accurate electric current transducer is a key component of any power system instrumentation. The design approach is to redefine the interface point as to input the analog to digital conversion function used by each of these measurement systems.
