Product description Transformer Standard current transformer are also called precision current transformers, current transformer standards, standard CT and current transformer standards. Transformer standards are divided into current transformer standards and voltage transformer standards. Standard current transformers are used in the error test of transformers. Used as a current transformer calibration standard technical parameter Temperature -5 40 Relative humidity 80% Rated Primary Current 5-5000A 5A,1A Rated secondary current 5A 1A Accuracy Class 0.05S Allow long-term work under the rated current; More than120A across the core. Precautions The current of standard CT and tested CT must be the same in CT calibration. Follow the given wiring diagram strictly. Test whether the load box is accurate or not before calibrating the transformer. Forbid secondary winding opening during the calibration. Select demagnetization before calibration.The wiring diagram is shown in figure 5. Short out the secondary winding before cutting off the power when the demagnetization is finished. Principle wiring diagram of CT with large current generator is similar to above diagram. They are the same except the output winding of large current generator and primary winding of transformer are the same one.

Resin cast current transformers are available for metering and protection application. These current transformers are mainly fabricated according to client’s specification. Ct coils are encapsulated in cast resin (polyester / epoxy). Secondary terminals are provided with either screws or studs. The main insulation between primary and secondary and earth is obtained by this epoxy resin. These transformers are of compact design with high mechanical and electrical properties. These are non-hygroscopic and hence give very good insulation properties even in given humid conditions. General particulars Rated voltage: 11 kv Rated primary current: 100 a Rated secondary current: 1a or 5a Rate burden: 5va Rated frequency: 50hz Accuracy class: 0.5 or 0.5s Temperature: as per is-2705/1992 Highest system voltage: 12kv Insulation level: 28kvrms/75kv(p) Stc: 13.1ka for 1 sec Continues thermal current: 1.2 times of rated current Core material: crgo Copper wire material: enameled wire as per is-4800 part-4 or iec-317 Insulation class/material: epoxy resin Secondary terminal: m5 brass bolt with nut &washer or m5 threaded bush with screw &washer Primary terminal p1 & p2 size and material Mounting base: ms 5mm thick zinc plated Rountine test :as per is-2705/1992
The initial magnetic permeability and temperature stability between nanocrystalline soft magnet alloy and permalloy are similar. Under the same conditions of core sizes and characteristics, the weight of the former is much lighter (about 1/3 lighter), cost much lower. Applications: Electronic kwh meter Precise power meter Overcurrent protection in mechanical control apparatus Current control in industrial automation Good thermal stability Paper ctn
