Current Transformer

Low Voltage Capsulated Current Transformer - : LV-CTs Sari-SEG Low Voltage Capsulated Current Transformer Technical Data Primary Voltage : 0,72 kV / 3 kV Frequency : 50 60 Hz Color : White Standard : DIN 42600 / IEC 185 Encased : In Flame Retardant ABS material Standard secondary current : . . . / 5A ( . . . / 1A on request) Standard primary rating : 50 , 60, 75, 100, 150, 200, 250, 300, 400, 500, 600 Class of accuracy : class 3, class 1, class 0,5 Accuracy limit factor or Over current factor : The ratio of the rated accuracy limit primary current to the rated primary current.For measuring current transformer , class 1M5 means the current error is 1% and the over current factor is 5, where at 5 x In the composite error should be greater than 10 %M is identification letter for measuring purpose Rated accuracy limit primary current :The value of primary current up to which the transformer will comply with the requirement for composite error Rated primary current In : The value of the primary current on which the performance of the transformer is base. Rated continuous thermal current :The value of the current which can be permitted to flow continuously in the primary winding, the secondary winding being connected to the rated burden, without the temperature rise exceeding the values specified. Rated short-time-thermal current Ith : Ith = 60 x InThe r.m.s value of the primary current which a transformer will withstand for one second without suffering harmful effects, the seconday winding being short circuited. Rated dynamic current I dyn. : I dyn. = 2.5 x Ith.The peak value of the primary current which a transformer will withstand, without being damaged electrically or mechanically by the resulting electromagnetic forces, the secondary winding being short circuited.
