Optical current transformer ppt
WebThe Magneto-Optical current transformer is based on the Faradays effect. fGenerally, this phenomenon can be described as follows: = V B.dl is the Faraday rotation angle, V is the Verdet constant of magneto-optical material, B is the magnetic flux density along the optical path, l is the optical path. WebIn general, magneto-optic effects break time reversal symmetry locally (i.e. when only the propagation of light, and not the source of the magnetic field, is considered) as well as Lorentz reciprocity, which is a necessary condition to construct devices such as optical isolators (through which light passes in one direction but not the other).

Drawbacks of Current T/f • The insulation structure has to be designed carefully to avoid breakdown. • Electric current path of primary bus has to be designed properly to minimize the mechanical forces. • Violent destructive … WebDefinition: A current transformer is a device that is used for the transformation of current from a higher value into a proportionate current to a lower value. It transforms the high voltage current into the low voltage current due to which the heavy current flows through the transmission lines is safely monitored by the ammeter.
