Current Transformer with DC immunity series is a star product. It is one of the key measurement components in the meter. The meter accuracy is decided by the CT accuracy. CT core is quite different from the traditional ones foreign CT manufacturers used to use. It's 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.

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.

Features:
- Special double core structure. One core is for AC measurement, the other is for DC
- AC measurement capacity is 20-30% higher than rated current
- DC measurement capacity is more than 71% of the rated AC
- High accuracy. Complitely suitable for high quality kWh meter with Class 0.5 or Class 1.0;
- Typical meter measurement error with DC influence is within 0.5%-2% for 0.1 Class CT.
- Small phase error. Typical phase shift is at 1-15'; Additional compensation not needed
- Good insulation between Primary and Secondary, more than 3kV.
- Reliable and stable performance at different temperature conditions
- Frequency: 50Hz/60Hz Ambient Temperature: -40--- +85 centidegree
- Many kinds of desirable bus-bars connected to the CT are available
- RoHS Compliance is available on request.
