Secondary Wire Type Current Transformer, CT Metering
Easy fixing inside meter, mounted on the bottom case.
Strong insulation voltage between the primary and the secondary ＞4kV/1min
Attractive appearance, casing color is available on request.
Simple assembly, saving production cost.
Easy connection to the primary cables/bus bars of latching relay.
CT without DC Immunity
Current Transformer, as a current sensing part, has high accuracy, small phase shift, smart size and big measurement range. Comparing with other sensors like shunt, the cost is higher, but it’s more reliable and precise, so they are extensively used in the energy meter, electric devices with overload protection and ground detection as current sensing.
Features
AC measurement capacity is 20% higher than rated current, 480A max.
High Precision, suitable for kwh meter Class 0.2, Class 0.5, Class 1.0, Class 2.0.
Typical AC current measurement error is within 0.02% at lb test point.
Typical phase displacement < 15′, additional compensation is not needed.
Big load capacity, up to 100ohm for 0.1Class CT.
Very reliable and stable performance at different temperature conditions.
Good linearity, it support automatically software calibration.
Different type for different fixing and assembly easily.
Quick connection to PCB available on request.
RoHS Compliance is available on request.
