1. Current Transformers (CTs) Transfers larger currents into much smaller currents based on certain ratios, which helps protect and measure electronics. According to electro-magnetic induction principles, current transformers are made by closed iron cores and winding coils. First winding contains less coils and second winding contains more coils, allowing a larger current to be transferred into a smaller one.
 

Utilizing self-developed nanocrystalline and amorphous materials which are produced by effective solidification technologies, enables VAC CTs to satisfy requirements for all types of technical standards and be widely applied in power measurements of various modes. Along with the birth and development of the high accuracy electronic metering industry, depending on the technology, advanced manufacturing and abundant experience, VAC has always been the leading manufacturer within the industry.
 

2. Strengths
The amplitude, largest primary current and phase error linearity of current transformer are determined by core materials. The best materials are required to have high magnetic permeability and relatively high magnetic flux density. VAC current transformers made with supreme amorphous and nanocrystalline materials possess the advantages listed below:
(1) Small volume, high linearity of phase and amplitude error
(2) Convenient compensation to phase and amplitude error
(3) Extremely low temperature influences
(4) High DC tolerance under direct currents
 

3. Application
Smart Meters
