Current Transformer with DC immunity series is a star product. CT core is quite different from the traditional ones foreign CT manufacturers used to use. Its created and developed by our engineers after great efforts fews years ago. This kind of CT have been approved and purchased in bulk by national and international meter manufacturers.

CT is one of the key measurement components in the meter. The meter accuracy is decided by the CT accuracy. Oswell is always insisting on supplying high quality parts for the customers, so we pay more attention on the production and process control. We are the ISO9001-2008 company and always responsible for the quality.

As the electric meter is smarter, the components will be smarter and smarter. Some customers design the PCB with CT mounted, which will save some space for the meter. Therefore PCB-mounted type is very popular in the market. More and more meter manufacturers choose this type and match the busbar on their own.
