MAGNETO-OPTICAL CURRENT TRANSFORMER

SEMINAR ON MOCT: Accurate current sensing is an integral part all instruments of power system. To measure the energy flow and conventional power plants using inductive current core transformers and coils. For high voltage applications porcelain insulators and oily materials will be used to insulation products between primary and secondary bus windings. isolation facility must be designed carefully avoid the limitations of the electric field, which could cause the insulation ventilation. The route of the bus power must be primary well designed to minimize mechanical stress on the primary cable failures. The reliability of the traditional high-voltage current transformers were interviewed because of their Violent destructive bug that caused fires and shocks adjacent devices in change, and electrical damage to relays Power outages.When the circuit functions within higher voltage levels, and goes to more conventional power processors increasingly bulky and expensive as the iron core saturation under fault current, low frequency response, it is difficult to obtain accurate current signals Power system transient conditions. In addition, concern, and control techniques and computing devices are digital protection introduced in power systems, conventional current transformers have caused further difficulties, since it is likely to introduce electromagnetic interference in the ground loop in digital systems. This requires the use of an auxiliary current transformer or optical isolator to avoid such problems.
