Description

Nice quality high permeability Permalloy core or aminated silicon steel core Current transformer​ widely applied in electronic energy meter, power transducer, RTU, etc

For our current transformers, which are produced by using high permeability permalloy core or good quality laminated silicon steel core, inflammable epoxy resin and case with our high precision toroidal winding machine & current transformer testers, steady quality and reliable safety, are widely applied in electronic energy meter, power transducer, RTU, electronical monitoring meter, power factor compensator, digital meter, motor control, industrial control system, electrical meter equipment, etc.

Our precision current transformer's amplitude error and phase error are tested by using high precision tester, elow is the tolerance table:

CT05, CT07, CT10 are micro precise current transformer, which are widely used in power transducers and electrical monitoring systems and RTU, the typical application circuit refers to below drawing. Based on rated primary current, an induced current will be created in secondary; customers can adjust the resistance value in output to get the required output voltage, and capacitor C and rheostat R are used for compensation; if compensation is not required, and capacitor and rheostat are no need to be connected. IC in below drawing is a common operational amplifier; a better operational amplifier can reach a higher precision and better stable function. The accuracy of resistor R in below drawing is required to be less than 1%, and temperature coefficient is less than 50PPM. R=V0/10(KΩ), generally speaking, C is requested between 0.01~0.033uf, R is requested between 150KΩ~300KΩ (R, C can be calculated by without compensated current transformer).

The second application is without operational amplifier in secondary, refer to drawing (2), add a standard resistor RL in secondary, then a linear output voltage can be got. A non-linearity is less than 0.1%, once increased loaded resistance RL, a higher output voltage can be got, linearity will not occur, so, it is better not to choose a higher resistance value which is suggested in this catalogue.
