CT009

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 ofCT 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 accuracyis 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 andprocess control. We are the ISO9001-2008 company and always responsible for the quality.


As the electricmeter is smarter, the components will be smarter and smarter. Some customers design the PCB withCT 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 thanrated current
★ DC measurement capacity is more than 71% of therated AC
★ High accuracy. Complitelysuitable forhigh quality kWh meter withClass 0.5 or Class 1.0;
★ Typical meter measurement errorwith DC influence iswithin 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.
★ Very reliable and stable performance at different temperature conditions
★ Frequency: 50Hz/60Hz Ambient Temperature: -40℃--- +85℃
★ Many kinds of desirable bus-barsconnected tothe CTare available
★ ROHS Complianceis available on request
