VI I current to be measured,? 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.
Magneto-Optical Current Transformer Technology MOCT | Seminar Report, PPT, PDF for ECE Students
Do you have PowerPoint slides to share? As no metallic wires are needed therefore it provides better insulation.
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.
Are you interested in this topic. 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 to enclose the optical path in the current carrying circuit. The accuracy of MOCT is so far insufficient for the use in power systems.
This MOCT is widely used in power systems and substations nowadays. Auth with social network: The outputs are send to photo detectors. They are all artistically enhanced with visually stunning color, shadow and lighting effects. Transformers are designated to be most efficient when operated at full rated There is truly something for everyone!
It appears that the newly emerged Magneto-optical current transformer technology provides a solution for many of the above mentioned problems. Temperature and stress induced linear birefringence in the sensing material causes error and instability.

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

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. J C Santos ,M. The signal is brought down to signal processing unit by means optical fiber cables. Share buttons are a little bit lower. No need to use metallic wires to transfer the signal and so simpler insulation structure than conventional current transformer.
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.
These Key players compete based upon pricing, quality, Technology and reputation. To measure currents, power stations and substations conventionally employ inductive type current transformers with core and windings. 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.

Published by Marilynn Young Modified over 3 years ago. And there is a growing interest in using Magneyo-optical to measure the electric currents. 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.
Many of them are also animated. Describe the components of an ideal transformer. PowerPoint Templates – Are you a PowerPoint presenter looking to impress your audience with professional layouts?
